Because the game is catered to proper gamers, not to people who like pet battles and 10 minute semi-afk dungeon runs. I don't think it's going to make it due to the high requirements put on the player, half of the MMO base will consider it either too hard or "too much effort". However, it's a really nice idea and I wish they'd just have put a bit of a different shell on it (not graphics but theme).
