[serious]where to sell video games

My oldest brother gave me a bunch of his video games. Out of the 21 games I have now, I only play 3 and I'm looking to sell the other 18, but not sure where. I'm hoping for at least $30 out of the 18, but since some of them are so old I don't think they will sell. Any ideas where I could go to get the most money?

eb games, local pawn shop, ebay, etc.

There may also be a specialty store around you somewhere that looks for classic video games.
