Well prices I know so far as of selling it to Gamestop are-Gamecube(20-30$),Ps2 fat(30-35$),X-Box 360(250-280),I know they will let you sell the guitar and the guitar Hero game seperate and will equal around 60-65$,X-Box (20-30$),DS fat(50-60$).No where likes to take OXm discs(which is gay),The wii online you might get around 300-350 depending on where you sell it such as amazon or ebay but gamestop will only give you 200 for just the system.The BK games altogether are worth like 6 bucks. Hope this helps I know some of these prices just cause ive sold some of my stuff to gamestop and I look at amazon a lot.
