Guess I meant to say "Action game". I'm looking more for 3d action games, vs 2d "beat 'em ups".
They're definately two different beasts, as the 3d variety tend to be more combo driven and execution dependant, vs classic 2d brawlers like Final Fight or Streets of Rage (Although obviously modern 2d beat 'em ups adapted a lot of 3d action game mechanics..)
Ninja Gaiden 2 is probably my favorite action game. Get the vanilla release on the Xbox 360, it's a serious ball buster. One of the few action brawlers that doesn't hold your hand. Same with vanilla devil may cry 3, that one might be worse.
