Jet Li's Rise To Honour was absolutely awesome. The shooting segments were utter tosh, but it had one of the best fighting control mechanisms in any beat-'em-up game I ever played. It helped that Jet Li did the actual fight choreography and motion capture for his character -- and he was fast and fluid enough so that just moving the right analog around made it feel very cinematic. That game still has an unrivaled combat system, and it's a shame we don't have it in any other beat-'em-up titles, but it would take an excellent talent like Jet Li to make it viable.
