If you don't mind a more top-down approach see if you can pick up an old title called "Titan Quest" and its addon "Immortal Throne" - it's a diablo-like (top-down hack and slash, sometimes called an Action RPG)
Other than that, I think the fighting in Batman: Arkham Asylum has an excellent hack-n-slash feel to it and may well please.
Agreed - Titan Quest with Immortal Throne should be available pretty cheap. You might want to try the FATE series also, Fate, Undiscovered Realms, and Traitors Soul. Hours and and hours of playing time. JMHO, Dave
