Alright, I've been given judgeing ability due to my Livestreaming, so here's my votes.
Just a bit of note, I went out of my way to give Livestream time for the less popular games, and this influences my choices:

Mario:
Super Mario Fusion Revival
Tanks! Tanks! T- oh, serious answer? Dur. Well, the crossover elements are neat, and the level designs show a lot of potential.

Metroid:
Rendzevous Delano
I didn't play AM2R so I can't fairly vote for that. Of the few Metroids I did play, this is the one that was good.

Zelda:
BS Zelda Map 1 + 2 Lite
Because I'd be a SUCKER if I didn't vote for a booth I submitted myself.

Misc:
Fire Emblem: Elibian Nights
For the Fire Emblem fans! A nicely done ROM hack.

Game of Show: BS Zelda Map 1 + 2 Lite
I'm pretty sure this is gonna be disregarded, but aw, well! Worth trying!

Runner Up: Fire Emblem: Elibian Nights
ROM hacks don't tend to get enough credit in the fangame community.

2nd Runner up: Super Mario Fusion Revivial
An actual fangame for this one.
