I like Guild Wars. That's pretty much it. Very good storyline, (IDK about others, I've heard that if you actually take the time to read WoW's story, it's also pretty good) early level cap which makes players focus on improving their own skill rather than equipment farming, graphics that still look pretty good, extremely team-based tactics and very good class interactions that can frequently break the MMO Trinity, (Tank-Healer-DPS) and interesting PvP metagames.
Yeah, I like GW a lot. GW2 should be a lot better.
