I got the idea to do a little backwards compatibility-related survey here.
The questions:
-2600, or 7800?
-PS1, PS2, or PS3?
-Xbox, or Xbox 360?
-Gamecube, or Wii?
-Game Boy, or GBC?
-GBA, or DS?
And here are my answers:
-2600, or 7800? - None, as I currently don't own either system, but this will change as I'll be getting a 2600 soon.
-PS1, PS2, or PS3? - PS2, with 110 games. I have 85 PS1 games and don't own a PS3.
-Xbox, or Xbox 360? - None, as I don't own either system
-Gamecube, or Wii? - Gamecube, with 72 games. I don't own a Wii, so there's not much of a competition here.
-Game Boy, or GBC? - Game Boy, with 58 games. I have 24 GBC games.
-GBA, or DS? - GBA, with 87 games. I have 20 DS games.
So, what about you?
