I can't figure out what kind of game to make. I want to make a Star Trek one, but meh. Not a huge fanbase there. I want to make something that everyone will want to play.
Make a Naruto game!

Oh, wait...
tooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo ooooooooooooo many
It was a joke...
You should make a game you would enjoy, do not worry what the people would like because there will be people who join anyways.

Unless you make a StarTrek game. Then you'll be all alone.
Make a city building game, or a futuristic rpg.
Get the drawing board out, and think up a game (perhaps use something for inspiration), then take it from there. A decently made, original game will go further on Byond than alot of people think.

Then again that doesn't mean it's a sure hit, it could always still flop just like any other game.
There is already a futuristic RPG being made. >.>
