Never played it ;D
Is it really as good as people keep saying it is?
Not really, it's over hyped. I mean sure it's a fun game for a run out and kill as many people as you can before you die type but ultimately it's not really compelling, so far Reach is the only promising one because it's supposed to tell the story of the planet Reach before it's destroyed and supposedly able to be used with Natal, although I'm not sure if that's verified yet...
Honestly COD:MW2 is better than Halo but Halo is still up there...just not that high lol. Essentially ODST is halo 2 and halo 2 is a little better than 1 so each one is slowly getting up there.
Summary: COD:MW2> ODST; Save money til Reach comes out.
