Galaxy 2 or Metroid other M. Whichever releases first.

Monster Hunter 3 (Tri)

all the games mentioned are note worthy but seriously one game only for 2010, then you should think of how much replay value you're aiming for.

typical RPG, 40 to 80 hours... and most other games are even shorter so you better play real slowwww hehe.

GT5 is the only one that will have replay value for the hours but I can't see my self playing a racing sim for that long as the ultimate goal is to own cars and the variation of the same cars.

I'll stick to something that I will and can put down over 5000+ hours.

Either GOW3 or GT5 I'll be satisfied no doubt.

Heavy Rain.

Hm one game ...
just one game ...
one game , one game 1 game ...
cannot compute ...
system error ...
shut down initiated this program will now be terminated.

if available in '10, Versus XIII. otherwise XIV. (my second choice would be XIII, but XIV will take more time before it gets boring^^)

Endless Ocean: Blue World or Last WIndow

only one ? damn...

I'd say Mass effect 2, but I'd hope massive delays for tons of other games !

probably mod nation racers. not exactly my most anticipated game for next year but the best compliment to the games i already own and continue to play.

Monster Hunter 3. Replay value.
