I've found a SEGA Mega Drive II years ago, probably somewhere in the middle of the GameCube era, it was the last one in a forgotten video games department. Bought it for about 55 euros, new. I moved to a different house and it's magically gone along of all my old consoles. I've also found, around the end of the PS2 era, in an also forgotten video games department, ICO Limited Edition sealed, which I still have.
I found a working slim ps2 with cables and a memory card when throwing the trash once. Another time I found an amiga 500. Don't know if it worked and I gave it away to a retro game shop. It was very cool just find these things. The favourite is the ps2 as I played a lot on it. Finnished Under the Skin and Liberty City Stories on it
I would say my fondest memory was finding a turbo grafx 16 system for sale at my local gaming store and purchasing it.I was quite excited. I always wanted to play it!
My favorite item would have to be my two N64 consoles. The one I grew up with was ny Transparent Green N64. I had both Mario Kart 64 and Super Mario 64. The game I played the most was Star Wars: The Shadows of the Empire. I also loved F-Zero: X, my second one Picked up at a yard sale last year, had 4 controllers and came with a box. Right now I'm hunting down a new copy of Kirby: Crystal Shards because I lost my old one.
I found a copy of Starwing competition for the PAL SNES in a garage sale for 1 buck, and there is only 2000 copies of this in the world I also found a boxed and complete copy of the zelda game & watch for 2 bucks
I found a complete in box sega saturn for 20 bucks at a pawn shop. The system was essentially never used.
My best find ever to date was a complete Death Return Of Superman for the Sega Megadrive £15 from a local gaming shop!! (2012). I have had other bargains but this is probably the best.
The two that I remember the best: Found an Atari 2600 at a flea market, CIB, with 2 games. All in good condition, paid $80 for it. Still has the price tag from when it was originally sold in stores. Got a Dreamcast from a yard sale free box.
