Dead or Alive started off using Sega's Model 2 board, which gave the game similar graphical treatments as Virtua fighter 2. Not only that, Team Ninja borrowed many fighting game elements from Virtua fighter 2 as well. These elements include: A punch button , a kick button and a hold button (This replaces guard as a face button) Attacks having high/mid/low hit levels. Attacks having priority over throws while in execution. Throws having 0 execution frames, and were considered guaranteed throws. When not guaranteed, a will execute. Throw not working on a stunned opponent. Throws having priority on a non attacking opponent (either blocking, holding, movement or in idle state). Rising attacks (both mid and low). Side rolling. Changes made from the Virtua fighter 2 formula include: Triangle system is based upon: Blow > Throw Throw > Holds Holds > Blows Every character having an exchange attack(Hold) Every character having a low throw Offensive holds (catch throws in other fighters) Every character having an offensive hold Combo Throws Combo Offensive holds Juggles based on a lower gravity Cannot re-float with a or Blows, throws and holds have larger knock back properties Danger Zones Ground Bounce(not otb) Techrolling is used for blocking Movement (such as crouch dashing) is easier to do. Movement in general is faster Damage modifiers/revisions is different Offensive hold vs Offensive hold result in a clash.
