Truthfully I think both Cod4 and Cod5 are great games, but Treyarch is just trying to make Cod4 with WW2, more maps, more guns, and more perks? I haven't played enough Cod5 to compare the amount of perks. If I'm wrong, somebody correct me. You wouldn't think it, but both Cod4 and 5 are extremely different on pc. I originally played it on Xbox and then I purchased cod4 and I realized it played a lot different. Maybe it's because I've got a laptop. And then I bought cod5 with the 50% off deal.
