maybe a new comp or better internet will help you with that :)
anyway.. i play wow, not much at all. it's a decent game, fun to do some instances and so on. pvp is good ^^
i recently tried SUN online, really good game. fast exp, short quests, intence fights.
maplestory - fun and cute game. too much grinding tho ^w^
grand fantasia - really fun game, kept playing it for a while. still got it installed but i just never log in :P
Lunia, pretty diferent game but it's great when you dont have anything to do cus you get easily addicted for the moment and 5 hours seems like 1 :)
well i've tried almost every free mmorps i've found so far, but i'm having hard times really getting into a game xD
