Can you trade games for games at game stop?

yes

All you have to do is go up to the counter and say that you want to sell whatever game you have.......but I would advise not doing that because they only give you 20% of what it's really worth

You can trade the game for the a dollar or so. -Abby Marie*

Yes. You can trade game boy games at game stop. You will get in store credit or cash for each game you trade in.

yes you can but they charge a small price
