As I understand it this is mostly about the silence of IW/Activision and their lack of community support. I didn't buy CoD2, partly because of my discontent with the way they handled the CoD1 community.
I mapped for CoD and CoD:UO, worked through their broken tools (the fact that you need to create a second directory named game with all the .pak files in order to get the compiler to work) and generally attempted to make the best of it. Community created tools bridged some of the gaps, but really the support was just lacking. Read this and you get a good feel for how the community feels about IW:http://www.iwnation.com/Forums/index.php?showtopic=17426
The fact that this server revolt is even happening (and I hope they are successful) shows me I made the right decision and stayed away from CoD2.This comment was edited on Nov 26, 17:49.
