Honestly, I'm game (pun intended) for either one, but, I like the first choice better, as Lovecraft/Tesla thing could be HORRIBLE. Or, as VicariousE said, Angry Birds-like profits.
I'm voting for the Sandbox game, personally.
Seems like it could be made in a better way than yet another G.D tower defense game.

The second choice.
You let the creative cat outta the bag with that one. Name alone could get you angry bird-like profits.

yes, profits do indeed sound nice, but I have no idea what i'd do with the game to make it stand out... Thank you for your feedback though :D
