I disagree. UNcharted 3, while I want to play it, I decided to see how much GameStop would give me for it. A new, 60$ game, little over a month old, commercials still on. Came with the Online Pass & Beta pass thing for another game inside. Pristine condition. They offered 15$...
You should sell the games as part of the bundle. I put in a year old game and got 4$. It came with 3 games, and the two I sold, sold for 4$ each. You won't get much more from people. Most will go to GameStop & buy used games for 13$-18$, even for games only a year old. Why buy from a random person? No offense, but you need to give them a reason to buy from you. Just cause you have it, doesn't mean they'll buy it from you versus an Official retailer. Incentive.
Also don't think 320GB VS 120GB means much on a PS3. You never store much data on them anyways. You could download every demo on the store and still have some space with the 120GB version. Plus people can easily buy a 1TB HDD for 50$(Once the shortage bull**** is over.), so not much incentive to pay more. I mean seriously, they charge over 100$ more for 320GB VS 120GB, which is hilarious as a 320GB HDD is like 20$.
Now you have the move. SO I'd say go for about 275$.
Include all 8 games + Move. Make sure to Format the HDD as well. Both controllers to.
Make no mistake here, you're not going to make back what you paid for all that. But you can make back 60-70%.
