Where do you want feedback on this to go? Ah, hell, I'll just throw some here.
I like the concept, but it's ambitious, and as always, I worry about abuse and dispute resolution. I like that it presents refined, standardized trade lists, and a way to search them near-instantly for what you want. But I worry about stupid children and other morons. They screw up trading via message board trade lists, and they screw up Goozex trades, even with the point system, all on a regular basis.
So I'm hesitant to jump head-first into the CAG Marketplace, not because there might be a bug here and there. Rather, I want to see what happens when it is stress-tested against unpredictable, stupid users. I'm not sure the beta's going to be enough to cover that.
That said, I have some suggestions:
1. I think that when you enable a game for trade, it should take you to a secondary page that
forces you to describe condition before the game can be offered. I really do not like "As New"--it's too open to interpretation, and too close to "New/Sealed". I'd replace it with either "Near Mint" or "Light Use", and then force users to always provide a detailed description of condition, with a suggestion nearby, encouraging the mention of scratches, creases in the manual, and so on.
2. I don't care much for the "Summary" page in another user's Wish List as it is now. It would be much more useful if it summarized that user's offered games by system. That way, if someone doesn't deal in Wii games, and sees a Wish List with nothing BUT Wii games on the summary, time is saved.
3. Common game peripherals, such as gamepads and memory cards, would be a nice addition to the database.
4. I know lots of CAGs use their trade lists for more than just videogames--items such as anime/gaming figurines and posters, DVDs, Blu-ray, PC parts, comic books and more. I think the best solution would be if the Marketplace TL had an option to display a big, fat link at the top to the user's old-school TL (or even a board post of the user's choice), with the post title as the name of the link. That way, users could tailor the title of their forum post to fit nicely at the top of their marketplace TL, if they wanted. For example, if a user was running a lowball auction in their forum TL, the top of their Marketplace TL could have a big fat link that says, "Check Out Someguy6108's Lowball Sale, LIVE NOW!"
Or you could just leave everything the way it is, and I won't use it.
