I traded in all my old PS2 and PSP games as i no longer needed them due to getting a PS3 and custom firmware on the PSP. I got about £80-90 for about 12 games which i was quite pleased with as i got myself some PS3 stuff.
Went in yesterday though to get a Wii remote, numchuk and component cable and took 6 DS games with me to trade in(got a R4 card) to my surprise i got £105 trade in on them so i got mario and sonic at the olympic games aswell.
I've been using GAME for years now, they've always been pretty damn good with trade-ins. I've always traded in my old consoles and games for the new ones. Got some damn good deals sometimes too.
Gamestation are normally cheaper to buy games though.
ive just took in cod4, vegas and sega rally and got 70 quid in store credit
well pleased with that because cod4 came out a week after i bought the 60 gb bundle, so took back motorstorm a week later and exchanged so cod4 only cost me 5 quid
paid 18 quid for vegas
and sega rally was free with the bundle
so ive just made 47 quid
