Unless your a hardcore fan like me. Don't bother this year.
The online element has improved the lag, but somehow made the interface cumbersome making it difficult to get a decent 2v2 game. Best version was PES6 on the PS2/PC. Why oh why do they remove groups, tournaments, 4v4 and online with 2 at a console.
Though 2v2 is fun when you get a game going and the online legends bit is a just a bit weird. Taking control of 1 player and goal hanging doesn't feel like football.
