Wish i could go back to the N64 (5th gen). The games were great, and the graphics were just good enough that you could use your imagination. Turok had terrible fog, but back then it wasnt a big deal, if anything it made the game feel more immersive.
I know people meme about the controller, but i didnt mind it. My problem was those terrible MadCatz controllers that you had to buy because they were cheap and you needed 4 controllers for Goldeneye and Perfect Dark. I think my rabbit also disapproved of MadCatz because he would only chew on the official N64 controller cables. Maybe they just taste alot better than the MadCatz. The accessories were also really cool. The Transfer Pak, the Controller Pak, the Rumble Pak, printing off stickers at Blockbuster, and of course the Expansion Pak.
Here's what i dont want to go back to: the original DMG Gameboy. The game library was terrible with Tetris being the only great thing keeping it afloat for many years until Pokemon came along and rescued this handheld. Of course i can list off some decent games for it, but nothing comes even close to Tetris or Pokemon. The only saving grace was that it didnt chug batteries like the GameGear or the Lynx (both of which i never saw as a kid)
