Pro Evolution Soccer 4 is like a fine wine, it simply gets better with age.
Whilst I agree with the initial comment by the previous reviewer (in that having played PES3, PES4 may seem inferior), I would also say that you just have to keep playing this game to see how good it really is.
Never has there been a game of fooball simulation where you can actually score real goals. I guarantee you that every goal you have seen scored this season, you can replicate it in this game, it really is THAT good.
It comes with the usual challenge of the Master League where your 'Dream Team' is gradually assembled. However now you have the added challenge of not just winning the International Cup etc. now you have to win each domestic league, which is no mean feat! This is done to build up PE Points which can be used to unlock a variety of goodies like Classic Teams, classic players and even new goal celebrations.
The game caters for newbies and casual games with an interactive training section which will have you mixing it up with the pros is notime which brings me to another amazing feature of the game- just like real football, anything can happen. I have seen many an established Pro Evo-er destroy another with constant attacks on goal, only to be undone by a lucky counter-attack or penalty decision- just like real football.
Even the refs are at it! Penalties are regularly given OUTSIDE the box, decisions constantly given the way of the home team, and scandalous red cards dished out, it all depends on the day, and that's the sheer beauty of Pro Evolution Soccer.
Yes, seasoned veterans may take awhile to adjust, but this is one game that you will keep just coming back and coming back to. If you like football, you'll love this game and for 17 quid ?! what you waiting for !!
