Hmm, my generation breakdown is roughly:
The few PC games in the list all handily fit into 6th gen. I didn't own a console during the 4th gen, though when 5th gen was in it's stride (about 96) I bought a MegaDrive, moving onto N64 in 99... and a GameCube 2 days after the European launch in 02. I sold the MD to help pay for the N64, so I didn't really get to experience much of it, only buying 4 Micro Machines games (which were awesome, I wish there was a modern equivalent, or that 1 would appear on VC) and a Lotus racing game (which was terrible)
I have also got Sonic, Sonic 3 and F-Zero on VC, but they are mostly too dated for my liking (I don't regret getting Sonic 1 though, that still has some charm)
From the 3rd gen I have SMB:Lost Levels and Galaga '90. Both on VC... SMB platforming is probably never going to feel too dated, though in retrospect I wish i'd got SMB3 instead of Lost Levels. I wish I hadn't bothered at all with Galaga.
Nothing at all from the 4th gen? Wow, that's shocking. 4th gen is my favorite, and the SNES constantly gets best console ever made awards (IGN in particular consistantly rank it #1, but with the number of quality of games this gen, I wouldn't be surprised if it's over taken)
As I said, I didn't get to spend much time with the megadrive, and my time with a real SNES is small and scattered: About 20 minutes of Super Mario Kart (battle mode) on a friends brothers console, A few minutes on a different friends SNES playing Donkey Kong Country, must have been around '94 as he moved to Canada the next school year. And maybe 20 minutes of Super Mario World on a cousins console.
So in total i've spent less than an hour on a real SNES, and 2 hours of F-Zero on VC (which with hindsight I would not have bought)
There are two games I have considered getting: Super Metroid and LoZ: ALttP.... but going back to 2D in series I started playing in 3D feels wrong, though I think it's more to do with control rather than the lost dimension... I can't stand being restricted to moving in only 8 directions. In addition to that, I would have to get the GC controller out for SNES games, and the shoulder buttons don't match (GC using analogue triggers).
