omg look at all the re-releases with God of War and....Riddick. If you include Wii, DS and PSP as part of this gen, then there might be more of a case, but there isn't much for next gen games. Hell, if you did that, the GBA would still be the biggest offender. Thing didn't even have a proper new Mario game.
the GoW bundle is a good deal, especially if you don't own any of the older games. Each game still goes for $20 greatest hits price, and basic math lets us know that $20 + $20 = $40, which is the price of this bundle.
