You would possibly get enough you could buy a pack of gum, that is assuming GS sold gum.
Seriously, if your games are complete, sell them here or if they're complete/mint(all have manuals, cover art), try FYE since they MAY be worth something there.
Check out secondspin.com and put in the names of the games you're trying to sell to FYE(in the search at the top, just change 'buy games' to 'sell games' then put in the games).
If the games don't come up on a list, you're sol because they may be worth as little @ FYE as GS.
In which case, sell them here.
