[POLL] WHICH CONCEPT SEEMS MOST INTERESTING?

None of the concepts are fully fleshed out and when ever I start working on any one of them, after a while it seems too much for me and I just have to put the project down, there is just way too much to think about, way too much to do.

This pole was made just out of curiosity and may or may not have any effect on the project I settle down with.

Note: For people who do not know what pokemon battle flo is you might want to look at the game profile before answering.

EDIT: Poll question too big, read below

battle flo sequel:
actual hps, stats screen, and several pokemon on both teams

grey scale:
depressing story, survival-puzzle adventure, survival (hungers, exhaustion and etc), whole game in grey scale, multiple endings according to the pathe(literally) taken

platformer:
roll to travel, can attack enemies from behind only, grass with higher priority then player enables hiding from enemies

untitled II:
rpg maker cross over (koh for rpg maker), tiles react diffidently when stepped on (hp up, mp up, battles etc), each character gains different skills according to equipment, about 20 equips

ghost:
be a ghost, psychological thriller plot, do ghostly things (whisper into ears, go through walls, possess people and etc), ghost energy bar

Can't believe no one is voting for untitled II.
