[H] Super Smash Bros. 3DS Demo Code (US only) [W] Various Games

I got four Super Smash Bros. 3DS early demo codes from Nintendo; I claimed one, gave a couple to friends, and had no idea what to do with the third... One of the friends I gave it to said he'd rub it in the face of another friend who paid 30 USD for his. I regretted activating mine, but decided to try selling the last one on eBay... Only to find that eBay does not allow the sale of digital games in this manner.

So I figured I'd try trading it for something on Steam instead. I've asked for things outside of Steam before in exchange for a trade, and even managed to get a GOG game this way, so I was curious to see if I could do things the other way around... Sure enough, there are no rules explicitly forbidding such, so I figure I'll go ahead and try it.

Here's a list of some games that interest me right now:

-Castlevania: Lords of Shadow: Mirror of Fate
-Castlevania: Lords of Shadow 2
-Age of Mythology
-Rise of Nations
-Divinity: Original Sin
-Star Wars: Empire At War

I should also mention that both the Lords of Shadow games are on sale at GamersGate right now; Mirror of Fate is only 5.10 USD, and I'd be glad to accept a trade for that.

I'm also open to suggestions for RPGs, strategy games, and action-adventure games (especially Metroidvania style).
