... Buy Metroid Prime Federation Force OR Paper Mario Color Splash in exchange? Would you do it? Keep in mind Federation Force is only $40 and Color Splash will most likely be $60 like all Wii U games.

If you do decide to buy any of those games which one would you buy and why? 

Paper Mario, sure! Metroid FF? I would rather fuck a goat

God that would be a crap move.

I'd buy Federation Force because it seems like it would at least be somewhat entertaining regardless of its bad, bad artistic direction.  Color Splash is more expensive and playing it would just make me more agitated after realizing that Nintendo won't make another classic Paper Mario game as long as Mario & Luigi exists or as long as Miyamoto still has some semblence of control within the company.

Damn right.

I'd rather drag my dick through a mile of broken glass then dunk it in a basin of lemon juice.

Fine.

Easier Scenario: If someone gave you either game as a present and you could redeem the demo, which game would you hope to find in the present?

None. I sincerely hope that they never come out with any demos for the public, nor any footage that is too revealing. Because you know that you're all just going to play the demo over and over, and by the time the game comes out it won't feel like such a fresh experience after all.

Federation Force. It's a spin off, and as a result is infinitely less offensive to me than having a full blown title look absolutely miserable. Plus, it's $20 less.

As the biggest Paper Mario fan I know, I will literally buy anything in that universe, so this would be OK with me lol. I loved sticker star and SPM for their own unique things and I'm sure I'll love color splash, though I doubt as much as ttyd.

I have no interest in Paper. But Fed Force can F off. I'd get paper.
