Is there any Xbox360 game worth playing that won't be out on PC?

[CrazzyMan]

practically NO.
x360 is a "CHEAP"(rrod+online for money) alternative to PC.

on x360 i would play:
kameo
pdz
graw(other version then on pc)
crackdown
dead rising(still not confirmed about pc port)
doa4
pgr3/pgr4/forza2(not a racing fan)
ace comabat 6(still not confirmed about ps3 port)
blue dragon
lost odyssey
halo3(though average graphics, and probably won`t be ported this year)
That is all after TWO years. Would take around 3-4 month of single player gaming, not more.

Then there would come:
Too human(pc version possible)
NG2(ps3 version still possible)
Fable2(that also have pc port possibility)
halo wars (same here)
infinite undiscovery

So pretty much, unless you want to play games, as soon as they will be available on the market, there is no big use of x360, because there is no much x360 exclusive games, which would take your single player playing time for more then 3-4 month.

Of`course, you always can buy multiplatform games, they are still games and play for 8-12 month or more.
But for now from view of exclusive x360 games, x360 is not looking very attractive + still under rrod.
