In the end, someone will always complain.
Nobody will ever be happy. If the game went back to cod1 and cod2 sytle, people would complain. If it was another modern warfare game, people would complain.
For $50 theres plenty of games out there that are straight garbage (spore) but waw isnt one of them. Ive played cod1, cod2, UO, cod4 and theyre all great in their own ways. But comparing cod5 to cod4 isnt fair, theyre set in different time period.
But the early cod's arent all that anymore (you can even sprint, no custom classes) i mean i could list on and on what sucks in them.
Cod: waw is far from an expansion pack. Its set in a different time period, has new perks different weapons, enhanced graphics etc.
