No i dont like call of duty enough to pay for more than the game itself. Many other games ive bought dlc for, hello halo 3 and 4 ive even gotten map packs for. But mot call of duty.
Though i will say this would be the one to make me buy dlc if the maps were good enough because for the first time. Actually enjoy a call of duty game. That is when the game works the way it is supposed to.
I downloaded the maps for Modern Warfare, World at War, and Black Ops. Honestly, I could have spent my money on anything else worthwhile, especially after I found out that you didn't really need the maps to continue to play Black Ops. Hopefully Treyarch will keep that trend rather than when what they did for World at War, no map packs meant it was really, really hard to find a match (the reason I caved and got them for that iteration.)
I don't really plan on getting the map packs for Blops 2, but I may splurge for the first one, I will see how things go... (seems that the majority of my friends are burning out fast on this one)
