Half-Life 2, Mortal Kombat Deception, Halo 2, Unreal Tournament 2004, Madden 2005...those are just off the top of my head, there are several more.
At first I thought this was a good idea when I got UT2k4, the extra stuff included with that was actually useful, but it's spreading a little too much for my liking. How long is it before we start seeing stuff like Army Men special editions?
Does anyone even care about the extra stuff or do you just want the game?
If you're still struggling with this and have held onto the game, maybe the patch they've just released will help? There's nothing specifically mentioning your problem, but maybe it's part of the memory leak issue?
