from a business point of view, companies will try and recreate the halo experience just for the $.
although i still think all of the halo games were cheesy garbage, they offered nothing new, just did a good job of making a FPS
mgs on the other hand has always been one of a kind. and i loved it for that, but not everyone did
in my books MGS4 > halo 3 by far, like a light year
