I'd love to play in a metropolis city sandbox game. My idea is this;

Level: 12-16
Whole big town laid out, where players can play as citizens in this town. I'd love to see a high-RP low to no-combat game set in this theme, where politics could settle more than combat. I'd especially love to see with no alignment restriction, and a POWERFUL military to prevent excessive evil. This would also allow evil characters to set up shop just outside of the town or in nearby dungeons, allowing players to delve into dungeons where the player holds shop. Someone please make this a thing.

Sounds AWESOME! If its Adult too I am absolutely in!

I don't care if it's mature or adult, so that'd be fine with me.

Sounds perfect for World's Largest City. I'd likely join in.

I'd still be interested in playing this if someone is interested in running it.

Could be interesting.
