Riot Simulator

This would be fun as an RTS/wargame or as a FPS, or as both, (Like “Savage”). It would also work in a MMORPG with “permanent death” because you get lots of combat, but you’re more likely to be arrested or injured than killed.

Fun as a cop, fun as a rioter, and you can have rioters VS other rioters, even civil war scenarios with cops versus other cops. Someone could also play as a media cameraman, trying to get the who gets points for filming the bloodiest footage.

Cops would get points for arresting rioters, and lose them for hitting/gassing bystanders, while rioters would get points for smashing specific targets, loot aquired, spraypainting stuff on prominent locations, etc. and lose points for smashing the wrong stuff, (Local people’s cars and windows etc.) or hitting bystanders, media etc. (You lose more points if there’s media filming you.)

You could also play an undercover provocateur, whose jobs is to smash and destroy as much as possible, without the rioters or media identifying you. Or a rioter dressed up as a cop, doing the same.

Note molotov cocktails don’t explode like grenades, and cars don’t explode when shot!

Battlefield 1914

WW1 before the mud and trenches. Just think about it: the planes fly low and slow, meaning you can see and shoot individual players on the ground, and they can shoot you. Air combat is fought with pistols, rifles, and shotguns. Fast paced action with armored cars, cavalry, motorcycles…

Also, trench warfare seems ideal for a first person shooter with randomized levels. Trenches are basically a dungeon labyrinth, and the fighting is very close quarters, with grenades, bayonets, even shovels and clubs. Call of Duty has already proven this concept.

American warlords

Picture this: civilization has collapsed, and everything’s gone mad max Somolia-style. Everywhere is run by warlords who have made improvized weapons out of everything they can get their hands on. Cessena planes with homemade napalm, cars with “hillbilly armor” and machineguns, helicopers dropping pipe bombs, molotov cocktails launched from home-made catapults on the back of pickup trucks, flamethrowers made from propane tanks…

You get modern guns but the planes fly low and slow, you can beat the armored fighting vehicles if you shoot in the weak spots, and you get to do drive-bys your favorite cars. This could be the later levels in the riot sim - things would start with riots, that slowly degenerate into all-out civil war.

Much of the vehicle modeling has already been done for microsoft flight simulator, and various driving games.
