According to an interesting piece of analysis from GameSetWatch (thanks VG247), just one game has so far sold more than one million units at retail; Resistance: Fall of Man.

Based on figures from Group (who collate monthly totals that send the business world crazy), only the first title has sold more than a million copies (outside of bundles with the console), with just coming close.

Resistance 2, 2, and 5: Prologue are all still stuck in the 500 to 750,000 bracket - we're told.

Analysis from the article in question suggests that while have been pushing new IPs hard, they should really now be focussing on some sequels in order to garner some hefty numbers.

Of course, it's also worth noting that when game-console bundles are included titles like Uncharted have faired somewhat better than you might think; so perhaps Sony don't have too much to fret about.
