Half and video games

I've made on average about $15 per video game resold - so I've approximately made back half the money I've spent on the four games (that average about $30 each for DS). Not bad! I got to enjoy the games and only ended up paying half for them. It's a way better return than the books have been, though I'm mainly just trying to get anything I can for the books instead of just putting them out on the street for free (that's what I plan to do for a bunch of the ones I currently have listed that haven't moved despite price changes).
