I was super pumped for Goemon's Great Adventure and I got it and my copy was broken out of the box. When I finally got a working copy, I enjoyed it a lot.
I played a lot of Super Smash Bros. and I don't disagree with the GOTY pick. I do remember DK64's multiplayer mode, which was fun. I borrowed it from a friend of mine and enjoyed about the first 20 minutes of playtime.
Jet Force Gemini was a rental, I think. I just remember playing that game almost to completition, and then I saw all the bullshit you had to collect and put it down. A friend of mine recently played it to completition, or at least to the final boss, which is fricking impossible. I tried my hand at beating the boss, but I kept on getting lightning'd to death.
I played through Pokemon Snap with a friend of mine. I love that game, but I wouldn't pay more than $10 for it. So, I snatched it up when it came out on VC because that's a good enough price for me.
Game Boy-wise I was probably still playing Pokemon Red/Blue. I would've been in like 5th/6th grade and Pokemon was the **** then. A bunch of my friends got Super Mario Deluxe, but I don't remember too much of it. Pokemon Pinball was fun, IIRC.
I think I really wanted Conker's Pocket Tales and then heard about Conker's Bad Fur Day and was like "I want that." Then I read up about C's BFD and I was kind of dumbfounded. Still wanted it, though.
