Alright, I'll make a list as well and see how it closely resembles others (feel free to comment/add suggestions I may have missed). I also will prioritize Nintendo published games over others, since its easier to have in the mini that way.
My N64 mini collection (no specifc order):
1) Super Mario 64 - cause obviously.
2) Legend of Zelda Ocarina of Time - may be GOAT, so gotta be here.
3) Mario Kart 64 - It needs a Mario Kart, and battle mode!
4) Donkey Kong 64 - Nintendo owned, so no issue to have it on the mini.
5) StarFox 64 - again, owned by Nintendo, so easy to add.
6) Super Smash Bros. -Needs to be in this collection.
7) Wave Race 64
8) Mario Party 2 - Overall better than #1, and a party game, so it scratches of having that genre.
9) Paper Mario - Needs an RPG, and its the birth of a current Nintendo franchise.
10) Banjo Kazooie - it kinda needs to be here, and I guess MS willbe willing to cooperate with Nintendo. I dont see Conker ever making it, since its an M rated game.
11) Goldeneye 007 - Its too popular to not be in a N64 collection. Somehow, they make it work and this is in for sure.
12) F-Zero X - Again, popular franchise, would gain major points to add it in this collection.
13) Kirby 64 Crystal Shards - It need a Kirby game, otherwise its not a Nintendo collection
14) Pokemon Snap - Odd and popular enough that they add it, just for fun.
15) Star Wars: Shadows of the Empire - Again, hard not to include this. N64 had some good Star Wars games, so add this gem. This overtakes Rogue Squadron in my mind.
16) Glover - Gotta add some more good yet obscure games, so this is in.
17) Mischief Makers - Personal fav, and also a fan classic and great game. This goes in.
18) Turok 2 Seeds of Evil - Its Turok and another great FPS, so its in.
19) WWF No Mercy - I and many have so many young memories of playing the WWF games on N64, so one game needs to make it.
20) 1080 Snowboarding - Cause it needs a sports game, and Mario Tennis/Golf arent are memerable.
Damn, I missed a lot of gems.
