michaelleung: Buy him a used copy of FIFA and rename the title. He'll never know.
ElPixelIlustre: Watt?
Also, why would I want PES2006 or 2007 when I can play 2009? (PES saga has nearly the same gameply every year since PES3)
The reason he plays PES instead of FIFA is because it's a better game, the only thing FIFA has going for it is more licensed team/player names. Or so I hear, personally I have basically no knowledge whatsoever... was thinking of gifting him sensible soccer just for kicks, but a google search later that didn't seem so sensible.
PES2006 would be perfect though, I think that's the one he plays now, on his PS2, so it may be just the thing to turn him into a PC gamer.
He'd appreciate Football Manager as well, but that's not Konami, is it?
