Now that I have my username straightened out, I'll repeat my words. As I was quoted above, they are shooting themselves in the foot. All you have to do is look at the Mod Database awards.
http://moddb.com/ These mods, free to the public in an age of ever increasing prices, breathe life into new and older games alike. To have denied permission to mod the game IN A RESPECTFUL FASHION THAT ACTUALLY PROMOTES SALES is one of the most ridiculous acts in the history of gaming. Even 3dfx wouldn't have made a mistake like that.
