sony fanboys too dumb to know things about royalties and rights that the ps1 mini would have a lot of crap games to replace good games with high licensing and royalty fees. sony doesnt own many ip's of good ps1 games.
N64 mini can't have most Rare games so it would suffer a lot.
Yep, Nintendo doesn't have the rights to the N64's best games. They would need to relicense from Rare, RockStar, etc. Never happen.
Mario 64 Mario Kart 64 Ocarina of Time Majora's Mask Paper Mario F-Zero X Donkey Kong 64 (recently released on Wii U VC) Star Fox 64 Kirby and the Crystal Shards Pokémon Snap Pokémon Puzzle League 1080 Snowboarding Wave Race 64 Pilotwings 64
Oh gee 13 games right there that were directly made by Nintendo and one that shows that there's more wiggle room to the Rare situation than people seem to realize.
And since there's been a Mega Man game on the NES and SNES Classic so far, we could reasonably add:
Mega Man 64 (aka Mega Man Legends)
...and Konami's been in on these too, so let's say:
Mystical Ninja Starring Goemon Bomberman 64
Yeah i think people would buy this even without Rare's overrated handful of games (which, again, are clearly not as locked down as you seem to think).
