Ultima Online is the product of Richard Garriott’s idea for a fantasy game involving several thousand people who can play in a shared fantasy world. Prior games Hundreds of people allowed to play at the time Sami, Including Habitat(beta-tested in 1986), The Realm Online , Neverwinter Nights (AOL the view) and Meridian 59 ; However, Ultima Online is much better than these games, both graphically and in game mechanics. The initial team was composed of Garriott, Starr Long , Rick Delashmit, Phillips and Scott, a bit later Raph Koster, who became the lead designer. Koster wrote about “designer letters” and usually went by his nickname of Dragon Designer. Koster drew inspiration from prior online games,  such as DartMUD . 
The project started in 1995 and was presented to the public at E3 as ” Ultima Online: Shattered Legacy ” in May 1996. Originally claimed to have more than 3,000 participants in the preliminary alpha testing .  The development cost was much greater than traditional computer games; it relied on people hosting servers via modem. Ultima Online’s features include persistent player housing, skill-based character progression,  a craft-based and player-driven economy,  and unrestricted player-versus-player combat. 
An artificial life engine has been implemented in the game. This is an introduction to animal behavior that would be useful in the game.  However, this feature never made it beyond the game’s beta stage. Richard Garriott explained:
We thought it was fantastic. We’d spent an enormous amount of time and effort on it. But what happened was all the players went in and just killed everything; so fast that the game could not spawn them fast enough to make the simulation even begin . And so, this thing that we’re going to do, we’re going to be literally never- ever – ever -and we’re just coming out of the game, you know, with some sadness. 
Beta and murder of Lord British
Lord British was Garriot’s in-game alter ego , who was killed during an in-game appearance at Ultima Online ‘s beta test on August 9, 1997. During a test of the population stress test, a player known as “Rain Field”. Producer Starr Long blamed it on human error: Lord British’s character, like others, had been made invulnerable to this kind of attack, but by design the invulnerability did not persist over several game sessions. When the server crashed shortly before the incident, Garriott forgot to reset its invulnerability status. Shortly after, administrators banned Rainz’s account of the beta test for multiple exploiting, rather than reporting, bugs. According to Origin, he was not banned for murder but rather Beta testers protested Rainz ‘ The following are some of the actions that have been taken in the past, including the following: MMOCrun calls the most memorable event in MMORPG History.  September 1997 was the last day of the original beta test . [ clarification needed ] Shadowlords, demons, and other evil creatures slaughtering every character in sight.
Origin era (1995-2004)
In September 1997, Ultima Online launched and opened the first game servers to the public.  Upon release, Ultima Online proved popular, reaching 100,000 paying subscribers within six months, causing severe lag problems. In 1999, the company opened the world to support the rising popularity of the game, in Japan , Europe and South Korea . In 2000, Garriot resigned from Origin, taking Lord British with him. Game players created their own fanfictionspeculations as to why the Lord had vanished. In February 2000, a large in-world event had a massive army of undead lay siege to the Britannia city of Trinsic. The event ran concurrently on all servers over several months. Another server opened in Australia during this time. In May 2000, Ultima Online ‘ s second expansion Ultima Online: Renaissance Dramatically altered the game. It split the game world into two parts called Trammel and Felucca , one was a consensual PVP zone, while the other was non-consensual. In November 2000, Ultima Online’s first official fanfest was held, called the UO World Faire in Austin, TX .  In March 2001,Ultima Online ‘ s third expansion | Ultima Online: Third Dawn was released. It added a new area to the server called Ilshenar. This new area could only be accessed with a new game client that launched with the expansion. The original game client could be used in the previous server areas. In January 2002, Ultima Online ‘ s second official fanfest Was called Expired Online Worlds FanFest, aussi Held in Austin. Players were able to meet the developers, as well as Todd McFarlane . February saw the release of Ultima Online ‘ s fourth expansion Ultima Online: Lord Blackthorn’s Revenge. Notably, it enabled access to the areas previously only available to the third Dawn game customer. In February 2003, Ultima Online ‘ s fifth expansion Ultima Online: Age of Shadows Was released. It is the most important game of the game. Around March 2003 Ultima Online reached approximately 250,000 subscribers. In February 2004, Origin Systems shut down. Ultima Online no longer had a named studio managing it. Development headquarters moved from Austin to Fairfax, Virginia .
Electronic Arts era (2004-2006)
The sixth expansion, Samurai Empire , launched in November 2004 was Japanese-themed. It offered two new professions, the Ninja and the Samurai , as well as new Japanese-themed tile sets. New lands, the Tokuno Islands , were added, with the cities being styled after ancient Japanese cities.
Ultima Online was the first MMORPG to reach the 100,000 subscriber base, far exceeding that of any game that went before it.  Subscriber numbers peaked at around 250,000 in July 2003, but then began a steady decline. In 2008 the game had around 100,000 subscribers.  As of April 2008, Ultima Online has a market share of 0.6% of the massively multiplayer online game subscriptions.  This may be part of the 2004 release of World of Warcraft , which has quickly established a market share of the game and has attracted scores of players from preexisting games in the genre.
Expansion number seven, Mondain’s Legacy , launched in August 2005. It featured the second player race, Elves . The upgrade is a major upgrade, as did the crafting system. Spellweaving was added to the skills. Many new dungeons were added. This expansion was the first that was available online. Mondain’s Legacy was the last expansion, with updates becoming more irregular after that point.
Mythic Entertainment era (2006-2014)
In June 2006 Electronic Arts Purchased Mythic Entertainment , the Dark Age creators of Camelot . Mythic was tasked with managing EA’s MMORPG portfolio, including Ultima Online . That month was also announced that the anti-cheating software PunkBuster would be integrated into Ultima Online . This marked the first time PunkBuster would be used with an MMORPG to help curb cheating and exploiting . However, it was never integrated into the game, and in November 2006, Electronic Arts put the PunkBuster integration on indefinite hold.
In August 2007 Ultima Online: Kingdom Reborn was released. This is the first major overhaul of the client and artwork systems since Ultima Online: Third Dawn . The final expansion was Stygian Abyss (2009), which focused on the gargoyle race. After Stygian Abyss The development model shifted from expansions to “booster packs” that were intended to be smaller. However, the first booster pack High Seas of 2010 was also the last.
Broadsword era (2014-present)
It was announced on February 6, 2014 that development of the game would be transferred from Mythic to Broadsword, which would take over future development.

Todd McFarlane was hired to design the monsters and regions for the game.

In the end, Odyssey was canceled because of the development team dissolved.
Since the designers of Ultima Online wanted to Provide freedom and sense of agency, It was significant to allow players to act in a villainous role. The consequences of in-game criminality were adjusted over time. As explained by designer Raph Koster, “Being safe from evil is, in my mind, a tradeoff for the fact that you do not get to be heroes anymore, in that you can just opt out of fighting evil. When it is not challenging, it is not challenging, that people would rather fight ‘pretend evil’ than the real thing, but I do not believe it. . ” Eventually, the Renaissance expansion created large areas of the game in which it was not possible to harm other players. A significant spike in account reactivation was attributed to this aspect of Renaissance. [ quote needed ]
Ultima Online was educated player volunteers (“Counselors”) and settled in 2004 without admitting wrongdoing.  AOL had their personal train service staff hired, then shut down the volunteer program. Microsoft will shut down their volunteer program for Asheron’s Call .
