man, MW2 should have been much much better than it was. No big changes from CoD4, and a storyline that wasn't at all great (or original - MW2=Red Dawn)

The sequel bug hits again.

With BC2, you can really see the differences, heavily updated game engine, upgraded mechanics and game physics, better destruction, etc. Sequel bug didn't hit there
