You Vs The World!!!!!!!!!!
I found this game where people from AROUND THE WORLD plays (mainly Americans and Chinese), and is like a giant battlefield which uses a strategic simulation type of gameplay. Only downside is that it takes time for the "turns", which is attack or actions. If you are intrested just check it out.

If you are not interested in this game then some other online games that I would recommend:
WOW (GREAT GAME, but you have to pay : ()
Runescape (Addicting, graphics sucks)
monstergame (cool idea, too slow)
FFXI (pretty fun, but you gotta pay)
