I recently bought a psp, and got this with it.
Being a huge tekken fan since the first instalment, it was an obvious choice for me to get this.
I have played it loads and have no complaints at all.
Graphics are crisp and smooth, game play is as you would expect from a 1on1 beat 'em up, extra games are a good addition (gold rush, you beat someone up and get gold for the damage inflicted; time attack, fastest play through; survivor, one round, winner stays on; tekken bowl, 10 pin bowling; plus plenty more)
Custom characters are good too as you can make them your own (colours, clothes, accessories, etc) ideal if playing online.
Overall, 9 out of 10, so 5 stars!
Get ready, fight!
