I checked out Fallen Earth, and though it looks fun, I would probably enjoy it more as a single player console game, instead of an MMO. I tend not to enjoy the large, complex MMO games that require a lot of time and involvement. I prefer games that I can log in, relax, chat with people, and just do as I want, but still have that complex side that I can work up to, instead of having to dive into.
This is probably the reason why I played MapleStory for three years...>.< Glad I finally quit, though...but now it's LaTale, Dungeon Fighter Online, Grand Chase, etc...>.>
