Firstly, I don’t think it’s helpful to say that a game sounds too much like some other game. I think you should just ignore those comments.
Secondly, I’d say write out a longer blurb about each of the three games. Imagine that you’re pitching them. See which of the three ideas captures your interest most, which you’d like to write, which you end up having the most ideas for, or which just captures your imagination.
Personally I’m not interested in playing criminals.
I did enjoy both Neighbourhood Necromancer and Psy-High and the different ways they tackled being a school kid with powers. And I know that any take you do on the subject will also be different from those two.
Why good or evil though? Does anyone willingly embrace evil? Well maybe, it can be fun to be a villain but the super-powered often have other pressures on them.
Curse vs Blessing. Do you view your powers as a curse and wish to just be normal, or do you love suddenly being special and revel in your newfound abilities. Do you love being different or just want to fit in?
Do you keep your abilities secret, hiding who you are for fear that others will ostracise you, or target your loved ones, or think you’re crazy, and the government will show up and dissect you. Or do you instead set about letting everyone know what you can do. And do you decide to wear a costume, create an alter-ego, or just do it as yourself.
Do you use your powers for your own personal gain, or do you use them to help others?
For the whole being a normal kid, in school, going through the horrors of high school, well do you use your abilities to get revenge on those teachers who were nasty, on the bullies that made your life miserable, can you cheat at your exams, do you even need to do exams? Or do you instead use your powers to get on better with everyone, or throw it all into perspective, or help others so they like you more?
See, for me that’s the interesting things for the school one. But for you it might be something different.
