all the tomb raider games
I'm something of a noob... Ocarina of Time, Master Quest, Majora's Mask, Super Mario Galaxy 1 & 2, Bowser's Inside Story, New Super Mario Bros, Partners in Time, and Dream Team... pretty easy and simple games.
Oh and Kirby squeak squad! I love that game..Kirby Squeak Squad, no guide
thats it
Oh man, I want to say none, but I am fairly certain I've beaten a few Crash Bandicoot's and probably a few of the Spyro games, but then again I don't know about "100%" because back then there wasn't really a thing that told you, you'd just get to the end and it was over, so you could still have missed mini games/secret things etc etc. I watched my boyfriend complete one of the newer Laura Croft games to like 99% because he couldn't find ONE artifact. It was super sad, I think he went back and eventually found it anyways, but he's one of those 100%ers and always like goes the other way from where you're supposed to go to find every last hidden nugget in every game.
