I wasted 50 bucks on tekken 5. It is a horrible game. Virtua fighter 4 was much better. I know it's not billed to be a realistic fighter, that's why I have Pride FC, BUT I'm a no holds barred vale tudo fighter...i select that first guy on there i think his name begins with a C or something because he had gloves on that looked vale tudo... sure enough he is in fact a vale tudo fighter...i choose him and he has pro wrestling moves like king rather than jiu jitsu, csw, muay thai or something good like that...i find the inaccuracy appaling... but it's a decent game, a good rehash of tekken 3... it's not without it's redeeming qualities though... i'd give it a rent first before you drop 50 like i did...
Pretty much all of the styles in Tekken are "horribly inaccurate". You should hear the Capoeiristas complain about Eddy Gordo/ms. Eye-candy-what's-her-name. Or the boxers talk about Steve Fox. Or those who study Tae Kwon Do complain about Baek/Hwaorang. etc, etc. The simple fact is that it's darn near impossible to "accurately" depict a fighting style in a balanced fighting game. Particularly with something as nebulous as Vale Tudo, which isn't a style at all, but a catch all for the hybrid of styles used in No Holds Barred fighting (Vale Tudo literally means Anything Goes in Portugese, for those who don't know). I agree that whatever Craig is doing, it doesn't look like what I see in Pride, UFC, etc. Perhaps it'd be better to call his style "thug".
I'm straying from my point, though. My original point is that it's unreasonable to judge a fighting game based upon how accurately the style is depicted. I'm not by any means saying you have to love, or even like, Tekken 1, 2, 3, tag, 4, or 5, though. And I certainly won't argue that Virtua Fighter 4 is anything but an excellently put together, extremely techinical fighting game. To me they satisfy two different needs. Sometimes I like to play chess, and others, I like foosball.
