Valve: All Steam prices have been increased 300% in the EU because trolololol.
But we already pay 25% more than the Americans...
EA: OOO GOOD IDEA. MWUAHAHAHAHHAHAH
It'll strengthen our IPs!
Steam already has a gift inventory, where you can keep/trade your games until you add them to your Steam library. The reverse probably wouldn't be too hard, taking your games out of your library and putting them into a "for sale" inventory.
I'm not sure how the pricing would work though, since there are regularly sales where you can get games for up to 75% off. If you sell them after the sale is over would you sell for a % of the current price or a % of the price you paid?
If people have to state their own price they're willing to buy/sell at, I could see people buying multiple heavily discounted copies of a game just to sell it at a profit later.
