Both! Well anyway depends on you I guess, I would go for AC because of its singleplayer, I see LBP more as a time killer than anything else (a totally awesome timekiller though).

Yeah I thought about the online CO-OP, and I guess it makes it very worth it, so I guess I should go with R6 for now and wait till I get some money for NGS, but I should do it before the new games start to fall from heaven (Heavenly Sword, Warhawk, Assassins Creed, you've got my point)

I want to buy those 2 gamesbut can't buy them both for now:cry:. So I guess that someone could help me choose which one to buy first.

Well... not all free MMORPGs are that good or are at least boring with time, but you could google search some games; theres also private servers for many games, but meh, its your decision:roll:
