Might be a slightly older game, but it's still the cheapest online I can see for this game. You can get 2006 FIFA World Cup for the PC for £10.98 including delivery from Gamestation. CHeapest elsewhere for this is around £15.
Details: 2006 FIFA World Cup is sufficiently different from EA's aesthetically similar FIFA 06 - no faffing about too much with the management side of things for a start - and the strict tournament qualifying structure is a boon somehow. At the time of the game's original release, we're just a few weeks away from the tournament for real, and 2006 FIFA World Cup is the ideal warm up.
