I have just the thing for you, my man:

AGON.

A game about Greek heroes, being badass, being a braggart, and covering yourself in glory. GM-full, so I'm unlikely to run it myself, but rather wonderful beyond that. Not entirely crunchy mechanics, but enough that tactical decisions matter. If anything, a bit about the framework reminds me of 3:16 - Carnage Amongst the Stars (which remains one of the few GM-full games I will run at the drop of a hat and then drop it myself).
