This is very exciting. Thanx to trading sites like 99gamers I've been purchasing digital game via steam and other means (humble bundle) and you can list them for trade but it's a little clumsy actually making the trade.
Currently it's really hard to browse for games in peoples inventory thanx to the fucking trading cards. Games show as steam items just like trading cards so there is no way to know if a person even has games to trade.
My account, for example, has strike suit zero Mega Bundle and Organ trail in my inventory but so far I haven't even found a friend who has a game in their inventory to trade.
I hope at some point they can allow us to earn a badge or something, maybe having current CC info with a purchase in the last 30 days?, and then there will be a way to browse inventories of everyone who has that badge and make offers.
I'd love to see what people would be willing to trade for Strike Suit Zero Mega Bundle rather than adding it to my library!
Steam code stuff you'll still have to trade outside of this system because the only way to use a steam code is to add it to your library, you can only trade items that were originally purchased on steam.
