Question for the Puzzlers!

I'm going to be putting up a puzzle I made a few days ago probably sometime in the next few hours. While the end game is not a bundle game, I figured I could toss in some keys from bundles I've been holding on to. Figure I would take a short poll up to when I start my tricks and see what people would be interested in.

Please note, that while my puzzle isn't going to be Insanely Difficult (Or is it..?), for the most part it isn't going to be a google question and copy/paste answer puzzle. It's going to require some logic and puzzle solving skills in places, as well as a bit of extrapolating from sentences. So I'd prefer if those who are actually interested in working on puzzles "voted."

Sorry I don't have some better stuff, my friends end up claiming most of my extra bundle keys...

These are what I have available:
Lume

Gettysburg
A Game of Dwarves
Warlock - Master of the Arcane
Europa Universalis Chronicles Collection
Defenders of Ardania

Darwinia
Multiwinia
Defcon
Uplink
Hearts of Iron 3
Galactic Civilizations I: Ultimate Edition

Thanks!

[EDIT] Note: I'm going to be giving away 3-4 different ones, so feel free to list a few that catch your eye.
