Old-school at its best!
The real skill to this game would be to press the triangle, square, circle and cross buttons as fast as you can, more or less at the same time as going crazy with the d-pad. I guess there is some skill involved, but if you have no idea what you're doing then just go mad with the buttons, you do actually do pretty well, as long as you're in range of your opponent :P
Although you're playing this game on a PlayStation, you can't help but to naturally feel as if you're playing on an arcade system. The feel of the game just makes you think this, but I guess it's a good thing, considering no other game makes me feel as if to be playing on another platform! Seriously, if you like the first Tekken game, then this would be the way to go. Tekken 3 is a huge step forward too, aswell as Tekken 5, but I never got to play Tekken 4, but I'm sure it's inbetween somewhere around them two :P
I hope you enjoy playing this game if you consider buying it :)
