What old video games are worth real money?

I just moved and in the process found a bunch of old nes, snes and xbox games. Where can I find out which ones are actually worth anything?What old video games are worth real money?
You could try looking on ebay to see what they or selling for. But unless you find someone who really wants them you're not going to get very much. I can usually get nes %26amp; snes games for 2 or 3 Dollars, and xbox for 4 to 15 dollars depending on what game it is and who is selling it. You are lucky if you get $0.49 to $3 for older sport games. I hope this helps.What old video games are worth real money?
