Final Fantasy VII. I dunno why I felt compelled to do it. 100% in that game is a fucking nightmare of random chance. You jump through all of those hoops to breed the desired Chocobo colour and it's still like 25% chance or something and you must reset the system over and over and over. Fuck that game. Fuck it so very much. D:
I think I got close in Vice City but I know I didn't get the t-shirt. I did get all the packages, that's for sure. Such colossal time wastage.
Everything you can do in a single new game and new game + of Chrono Trigger, I did. Not all endings, but all items and all missions finished.
Wave Race 64
edit--- come to think of it now, I might have done 100% for Project Gotham Racing 2. Not sure on that.
