On principle, I would not buy the maps.I'm quite surprised at how many of you are willing to pay $15 for 3 new maps and 2 maps you've already played. Meh, this is part of the reason I don't play multiplayer games on consoles I guess =/
However, when it comes down to it, I don't want to be getting kicked out of lobbies etc just because I don't have the new maps.
Also, my little brother paid for most of it anyway so it was cool.
But yeah, after playing TF2, BFBC2 etc and getting all the stuff for free, £10 for 5 maps sucks. Especially when the CoD4 maps are so ass.
Finally, @ Bailout: This map fucking rocks. Easily the best of the new ones. In fact probably my 2nd favourite of them all, just behind Afghan.
