WOW wasn’t afraid to use good ideas and polish/improve upon them in all aspects.
Unlike a lot of the competition and releases since then that have the notion that “we’re not gonna do like wow and be polished and continuously improve…”. Not to mention their gamechanger - UI MODS.
Hey, LOTRO is great, but the engine is shit and it took them years to improve the solo->group aspect of the game, that probably bled away a lot of players. How fun is it to play a MMO when all the content is now “Large Fellowship” and you cant find anyone to group with -when-you-want-to-do-the-content-.
That said, WOW also was terrible in TBC when it came to group content, but at least they helped smaller guilds so you no longer needed 40 people…but it didn’t really shine until WOTLK with the dungeon finder introduction… and then latter with the raid finder and scalable raids, all great ideas…
RIFT also had a lot of great ideas, but nearly all of these came later on, when it went F2P. Such as a scalable mentoring(level) system (EQ2 let you mentor ‘down’ as well, if I remember correctly) and instant-adventures for world questing, at release it only had a terrible game engine and “Rift” events. Something Warhammer also did (also shitty engine) - but at least Warhammer let you make some UI mods again + it had the TOME - which was worth playing for alone.
EQ was good for its time, but it was absolutely not solo/short burst friendly and pretty ‘elitist’ when it came to end-game content.
DAOC was more solo friendly, and tried to encourage exploration by giving XP bonus for killing stuff in ‘new areas’, and the 3 realms/PVP idea was good for those who managed to grind that way.
Wildstar was pretty polished in almost every aspect, had a great engine, UI Mods, group system and everything… they just lacked the magic (and somehow they nerver got it…). They pretty much said straight out "We’re not gonna be accessible like WOW… ". If I remember correctly, they did not have any means of doing large scale content without a pre-established group and the PVP system they had was shit.
WOW also came out at a time when a lot more people were on the internets and ready for something new… What is funny is that the same year, if I remember correctly, EQ2 launched. Only one of these games became a success, and it wasn’t the one from SOE. Why do you think that is… Polish, innovation, A great game engine, not being afraid to take ideas from others.
- WOW was also the first MMO (I think?) to make a 64bit client available with much improved stability and performance :)
