Neocrisis: If you want a very fast paced fighting game, then this is not the one you are looking for. I find the fighting aspect to be extremely slow. I may be biased in that i have been playing Lords of Shadow which has a very fast paced fighting mechanic.
I know that these two are different fighting games but Fists is still too slow. However, once one gets used to it, the fighting does improve to a certain degree. The fighting also improves a bit more once you level your various moves.
