$15 Budget: Buy 3+ Games or Cards

I was going to get Skyrim LE, but there were other great games on my wishlist (Runner 2, Dishonored, Deus Ex, Dark Souls, etc) that were at a good discount. I'm a little disappointed with Skyrim's stilled discount, but I'm content with the games I've bought so far. :D

So I'm left with about $15 and I see two main possible options for me which are buying games or cards/badges.

Option v1 - Trine 2 Complete, Mirror's Edge, Mark of the Ninja.

Option v1.1 - Sanctum 1, AudioSurf, They Bleed Pixels, World of Goo, Rock of Ages, Q.U.B.E.

or

Option 2 - Cards: About 10 Sets = 1000 EXP = 5 Level Ups

Now getting cards isn't a big deal for me, but it's a possible option I can choose. My thoughts are Option v1 > Option v1.1 > Option 2.

Anyways would like some advice. ^_^ I know I don't have to spend anything. But I like gaming and I have $xx15.xx on bank account's balance and just want to make it $xx00.00.lol
