I've discovered an excellent MMORPG called Perfect World (
http://pwi.perfectworld.com/) It started as a Chinese-based MMO, and has expanded to include English-speaking audiences as well. It's free, but is actually really well-done. I think it may even beat WoW, but I won't know for sure until I get to a higher level. The character customization is awesome, the classes/races are nice, and the detail in the environment and spells is comparable to any paid MMO. The storyline is based around ancient Chinese mythology, and the music and environment (and NPCs) all have a really nice East Asian theme/look.
I may quit WoW in favour of this, and it definitely helps that it's not taking a $15-per-month chunk out of my wallet.
