More specifically Tekken 5: DR is One of THE greatest fighting games ever! Not as technical and complex as Virtua Fighter so a broader audience can pick it up easily, however the difference between 'noob' and 'pro' players are crystal clear. Also a well balanced roster of characters even though there are tiers theoretically any character can beat any other character. The gameplay is awesome and the animation feels alot more fluid than alot of other fighting games. Character designs are wicked and the english voice actors don't sound too bad at all. The fighting system is integrated wonderfully with all the technical sides of a fighting game, (whiff punishing, spacing, etc.) Also the fact that it reaches such a broad audience means you get to play lots of noobies at the arcades :D
Tekken Player: "Did you see that?! I just did a 8 hit air combo!"
Observer: "That's not realistic..."
Tekken Player: "STFU!"
