Some of these games are actually all right, and it may encourage people to buy the DLC. I bought the DLC for Borderlands after getting it free for instance. Otherwise, I would not have bothered with it since I thought BL wasn't my kind of game. Most of them are just 'filler' games for me and they won't keep me from purchasing games I want day 1.
