Jelly Battle
Virtual Family Kingdom
Second Life
Miniclip
Addicting games
Funny games
Bumarcade
Runescape oacie.com as well
freedesigames.com

Oh yes! These are some of the best. If you ask me, I'd say try all :) I love Second life. Came across Runescape through something I was following on Trackle, it's good too. Try a couple, pick what you like best and then choose.
I would try http://www.funpoles.ucoz.com/stuff It's my favorite of the 10!
