Do you have any ideas for a video game?

I’ve come up with tons of them, and I want to read some of what other people have come up with.

One of my games is an RPG, its very similar to Kingdom Hearts(gameplay and story), except, it has a modern present day setting like Pokemon and Earthbound(Mother). The main character has a weapon similar to a keyblade, becuase it also fires beams of light to unlock gateways.
