And that's exactly why I won't purchase any DLC. I may be missing out by doing this, but if I'm one less person playing a DLC map, hopefully fewer people will end up purchasing them, and then the developers will have to rethink how they approach this. Hopefully the conclusion will be that map packs are either become much value for money or, at best, free. The only acceptable charge would be for a whole chapter in a single player game (or perhaps 20 maps!).
I'm surprised the Riddick game has any downloadable maps so early though. Can we assume that from the time the game was finished, up to now, is how long it takes for this amount of maps to be developed? Nah. I think they were held back for a bit of extra profit.
