Most likely something on the Steam store that is similar in price to it, or has been on sale for around the same price. It's not all that simple a matter to go through my list and declare "these particular games are fairly even". And since you don't have a wishlist I have no idea what you might be interested in. There could also be some regional differences in pricing in certain cases, but if you want to take a look at my list and are interested in something enough to make an offer, you can just ask and I'll tell you if I think it would be an acceptable trade.
