The term good is such a generic term and can mean many things when talking about suppliers. Good as in reliable, good as in selling authentic games, good as in cheap and so on lol. I make this point only because if you are using good in the context of cheap, then you'll find it hard.
Video games and consoles don't have a huge mark-up on them to start with and far less mark-up using a drop shipping method. Combine that with trying to compete against big sellers buying in bulk and selling at a extremely thin margin on eBay and sites like it, makes the video games market a really hard nut to crack.
That said, I'm sure some are doing it, but it would be helpful if the support team know what format you are interested in, so they can find you some possible supplier leads to give it a try.
