it is superb. by far the best incarnation of VF so far. apart from the usuall involving gameplay, you also get the chance to customise your characters clothing as you progress through ranks ie. the more fights you win the harder your AI oponents become, and the more rewards you get for for winning.
There is also an indepth challenge mode, and a 'world arcade' where you can pit your skill against AI modelled on the worlds top virtua fighter players (mostly Japanese).
As with any fighting game, it comes into its own in 2 player mode, but it is an involving 1 player challenge.
i like both the Tekken and VF series of games, yet they are different,and some people only take to one and not the other. they are both great games however, and deservedly popular. Tekken is a little more accessible to beginners, but has hidden depth, VF is just deep from word go, and has to be learned the hard way from the beginning- frustrating, but very satisfying.
its an old game, so check ebay/amazon for used copies- should be cheap as air, and will be an outstanding purchase
