I actually haven't played alone yet, but with a few RL friends or old WoW buddies. I guess my point was just that by comparison to other MMO games like WoW or Guild Wars (or even D2 where there the ladder was competitive), this game isn't and won't ever make me feel pressured to commit more play time. I don't feel like 'the world is going on without me' the way I did when I played WoW. By this reasoning, I'm finding this game MUCH better suited to my adult life/schedule than something like WoW or Guild Wars.
