Firefighting game

So I've had an idea for a while now that I think would be super awesome.

Basically you're a firefighter in a city somewhere (NY would be the best recongition probably with the fdny but it by no means has to be set there.)

The actual firefighting can be set fps style, so you'd be looking through the scba mask, see the top of the helmet, etc. The different fires and other calls could be procedurally generated so that they don't get stale. Etc.

If you want to implement a leveling system, you could have the player work their way up from a rookie to a captian or chief, along the way giving them more and more responsibility just like would really happen. At a certain point, you could even have them driving the truck for a few calls and staying outside the fire providing the guys on the inside water.

I have a few other thoughts on this, if anyone is interested, but I'm sure you have thoughts of your own too. Just let me know if you make anything like this. The closest that ive ever seen is called fire department fd18 and it was for ps2 way back in the day, haven't seen anything like it since.
