Online RPGs

So I was just browsing Fry's yesterday and came across a game with a box cover I recognized from the wallpaper sets on cnet (you know, that site where I get all my monthly wallpapers). So I looked it up out of curiosity...

Guild Wars is sort of like Everquest, except with no subscription fee, and mainly skill oriented rather than level oriented play. Sounds interesting... though I'm not sure I want to get myself addicted to an online RPG when I already have MUD and RL vying for my time...
