How about Rock, Paper, Scissors?

chess?

Which also can be played with large numbers all at once:

Yes, another one of my games I did.

Which, if you have a chess set, not long enables you to play one game, but a number of variants using a normal chess set.  A thing about Chess is that it lends to people creating variants, so you also get a game system:

On the site is a list of more notable ones.   The nature of chess being what it is, also lent to myself creating a number of variants.

By standards people apply to videogames though, it is supposed to be a really good experience for playing.  Even if you play through once, it is supposed to be memorable.

Most important person? there must be something special about you that makes you most important... hmm.... I would play whichever game that has the sharpest parts so that I could kill you and use your body to regain electricity.

Civilization collapses? Poor Sid Meyer...

Hey, if I am creating some extreme end of the world fiction, why not put myself at the center of it, making myself the most important person in it?

A gotcha about your strategy is that it fails to account for the reality my body is not key to the regaining of electricity.  Because I design tabletop games, I didn't feel it in my interest to have my body have the ability to regain electricity.  

As for bits to use, I suggest getting ahold of Icehouse pieces.  They have sharp points at the end.  You might want to look into that.

It is horrible, because no one can play his game without electricity.

Hmmm... thanks for the suggestion. If your body doesn't regain electricity, I may still kill you or someone else, though. The frustration of lacking electricity may be overwhelming, I'll need to let it out on someone.
