Irrlicht Engine

Hi,

Lets say I'm making a voxel FPS. I'm thinking Ace of Spades or Brick Force. What libraries or engines go nicely with Irrlicht to achieve my goal of making a clone of one of these?

What libraries or engines I already know I need:
Physics
Sound
Voxel(maybe)

Thanks for the replies! Expect to see me on these forums a lot.

The subject says it all. I am experienced in Alllegro and PDcurses and have never programed using a 3d game engine. Are there any beginer mistakes I should avoid? And are there any simple programs I should try to make?

I guess I'm just a little overwelmed.

Thanks,
