im not used to this ebay stuff but tbh i think its a decent price but the problem is that the products are now preowned when they buy it so people are put off for high prices. I'll say about 425 - 450 start and 520 buy out, this, i believe, may interest more people, also give a bit of a bullshitting story, say you have played the games a couple times, people would be interested by this, i know i would.

also take pictures of all around the console and both sides of the discs if you havent already done so.

Hope i helped you in any way.

or ven 470 if you dont wana start too low, start 470

If it were a brand new, that'd be a good price. Since it's used (even if you used it only once), the value of it drops dramatically. You should drop the price by around $100 or so if you want people to actually pay more attention to it. But remember that other factors play in as well, such as how high your feedback is. Also, things of that high value sometimes do take a much longer time to sell than lets say something that's only $15, so just be patient.
