Maybe some different Arcade Games. ConSumo, Nut Shots, and Monkey Fling were unique in their own way. I hated the Racer Games, though, and glad they weren't needed for the 100%.
Buying all the clothes for the 100% should be dumped though. On my first run, it was about $3k for all that, most was useless shit a pussy wouldn't even wear. I did like the Customize option though, and that should be kept.
