First person view? That would probably require 3d graphics, which would make the whole thing a ton more difficult to create. I was assuming Crazy Rabbit was thinking more along the lines of a 2-d top view game. Which already would be very difficult and time-consuming.

(Also, not entirely unique. Savage 2 allows you to play as a Real Time Strategy Game, or as a first person shooter/3rd person action game.)

Maybe you could rig something interesting, where you control Jazz in a 2d, sidescrolling environment like Jazz 1 or 2, but he also has the ability to build buildings and units, and command them to attack various things. Although now we're heading more towards DotA, I guess.
