With sport titles your lucky to get $1 a game, maybe try and do an offer like 5-6 games for $5 shipped might get someones attention. Problem is no one going to want to spend shipping on a $1 game so you gotta almost offer free shipping. but to be honest do what I do with crappy sport games, take them to a local game store and use them as trade in for store credit. You'll only get like .25-.50 a game but at least it will add up towards something you want.
I personally only buy sports/kids games when I find them at garage sales priced $1 or under and most collectors feel the same way.
