So I've been thinking about that Apache game and this is basically how I would make it.
Backstory: It takes place in alternate history where a fictitious war between Germany and France started in 190X. Germany called in her current ally, The United Kingdom, and together (as usual) they roflstomped France. Due to new advances in military technology the war was extremely drawn out, much the same as WW1. Germany and the UK won due to heavy blockades chocking France out of resources from abroad.
This blockade caused a major social shift and caused the fascist ideology to raise 40 years early. The fascist faction usurped the government and started peace talks with the British/German alliance. The peace negations were extremely punishing to France but the faction accepted. However Europe started to become fearful of the fascist ideology and soon the truce was broken and France was heavily embargoed. This caused the government to be able to enact even more control over it's people making the setting more or less dystopian.
The game takes place in fascist ruled Paris in 191x which is over run with street gangs and other criminals trying to survive. You're the leader of a small ruffian gang based off the Apache gangs. It plays a little like X-COM, securing locations and expanding your influence against extreme odds (the government/other gangs).
The game mostly takes place in tactical maps where the gameplay is much like Fallout: Tactics. Top-down camera command a small squad of ruffians in a real-time pause-able tactical RPG. The game will have you "stalking" and "herding" the bourgeois into corners and alleys where they're easily robbed and tormented in safety. Later in the game more organised crime is needed and finally it evolves into a full-blown revolution against the government.
But instead of anything like this you're going to get "Call of Duty: Cock Slap, Gun Time". Have fun with that.
