Any differences?, you betcha. The controls are so different from Tekken, but yet the feel of the fighters with both series are very consistent and rich in Character, having their own unique abilities and traits. "KING" from the Tekken series would make a nice special appearance onto the Bloody Roar game as a secret character to unlock. Bloody Roar is awesome with an animalistic wit! Compared to the Tekken reaction time when using your buttons to spin off combos, I'd say there is a 4 second delay with Bloody Roar making the game very challenging, since its more on accuracy and timeing, whereas in Tekken you have agility, speed, and timing with the combos towards your opponent. If your a grea fan of Street Fighter, Tekken, Mortal Kombat, Guilty Gear, and Samuria Shodown, then yes you will also love this game. The graphics are perfect and smooth, and each time you play it gets interesting, plus with other things to do in the game like in Tekken. A great keeper, and be sure to collect all the Bloody Roar games on the PS-1. PS-2, and PS-3, there is no doubt that one day they will come out with game called DEAD OR ALIVE VS BLOODY ROAR!, that would be sweet. Or TEKKEN w/ Animal "RAVE" VS. DEAD OR ALIVE, yeah baby that would be Da Bomb!
