The reason is that MS only cares for the USA market, so all of the games are either FPS, shooters, action games, western RPGs and racing games; and with these image games with japanese and european appeal like Viva Piñata and Blue Dragon just bomb.
PS3 games are more varied; the only way the PS3 could fail in Europe is that MS moneyhats Konami so WE is a 360 exclusive.
That's the reason why the 360 will inevitably end 3rd place this generation of consoles.
