As ridiculously good as the Panzer Corps is, I think so far oxycutor wins my top prize rosette. like steve said, it's just so crisp - the black is so sleek.
Not wanting to put anyone else down by any means. Just putting one of the metal STanks together is a feat worthy of praise in itself. Mine is still in pieces from my numourous attempts to get it together.
once mine is fully re-assembled I might get around to posting a pic of it here.
