For me, I think it's the 3DO system. I'll never forget how advanced it was at the time, compared to what most people were playing. No matter what console, I only collect games I truly love or "want" to play, or games that I had as a kid and sadly got rid of in the past. And of course, the games that I'm nostalgic for, even if they're "bad but good". The odd-shaped big 3DO boxes are fun to collect, when I can find them. I don't care about the shovelware, but man, that Road Rash is still the best version of that game ever! And all those FMV games.. a lot of the best-looking versions are on that system. I'd play Sewer Shark on the 3DO over the Sega-CD version any day, even though I happen to own them both. The early CD-era was a charming time. They were experimenting with different ways to use the tech, and as far as game music, some of the best was during that time. Especially Shmups... I was literally listening to the Robo Aleste sega CD soundtrack yesterday in my car. Wow, i'm a nerd.
