I have a finished script of a videogame that I was working on since age 9. Since I intend to publish it, I won't reveal too many details.
The scenario is this: various gangs (warlocks, aliens, corrupt dictators, etc.) are passing a kidnapped princess around until it reaches the final gang, led by someone who wishes to abuse the princess' sealed powers. Several heroes went out to save the princess, but each one got captured by a gang, so now you control two brothers that go out to save the captured heroes and the princess.
That's as much as I'll reveal, since again, I do intend to publish it, and I dislike people stealing my ideas.
