Just some thoughts...
Wouldn't it be easier just to do what the TPB one does and just list the Name of the Game and platform (Super Mario Galaxy for the Wii)? Otherwise, the individual platform threads could get unwieldy and it could potentially be difficult to track?
That goes with David's idea...its not bad, my concern would be someone forgetting to put that in...and something shipping needlessly...
Maybe we can see what others are like to do and if it takes off...if it doesn't, well, I'll be upset, but that's life...
