I hope that's enough for now?

To me, the Dreamcast is the last batch of Sonic games. When I think of Dreamcast, I think of both the Sonic games, as well as Sonic Shuffle. When I think of Soul Calibur, I think os SC2 more, when I think of Resident Evil, I think PS1, and GCN more, but the Dreamcast was the home of 3D Sonic games. In my opinion, that's what defines the dreamcast to me. Besides, both games play very differently, and show two different sides of Sonic. Sonic Adventure 1 was more classic Sonic, where Sonic 2 was some weird new era Story.

You made a very good list, and thanks for keeping it easy on me and having the consoles in same order.

However one problem, if you look at the cover of Pokemon Gold/Silver it says Gameboy Color, not Gameboy. Although it's playable on a standand non color gameboy, I would still classify this as a GBC game.

So I didn't add your GBC games, but added you'r GB games, with the exception of Pokemon Gold/Silver.

Also, for DS, Brain Training, do you mean Brain Age? I didn't add your DS games because I wasn't sure, when you replay I will add all 3 Nintendo handhelds.
