One of the reasons WoW had 14 million subscribers

Intsant abilities were actually instant, unlike in this game, where instant abilities have 1-2 second delays, because i really need a silence with a 1.5 second delay....thanks SE /sarcasm

One of the reasons WoW has 14,000,000 subscribers is because it was released in a time where people were burnt out and miffed at other mmo's. There was no real competition. Most mmo's also weren't casual friendly. WoW brought mmo's to a wider market and got many people into gaming that were otherwise uninterested. For years it had no real rival, for years people developed connections, guild attachments, made friends, and etc. These people play other mmo's but then just get nostalgic for WoW moving back there. No game will likely hit that number of subs again unless it completely revolutionizes the genre in the same way.
