It's taken a while but the 6.3 million copies that Street Fighter II for SNES has now been surpassed by 2009's Resident Evil 5 at 6.5 million. That makes it Capcom's new best-selling title in history.
Of course if you want to count Street Fighter II Turbo's 4.1 million on top of that given that it took away sales from the original... Capcom has over 60 games that have cleared 1 million sales.
Resident Evil 6 meanwhile has achieved 5.2 million since its 2012 debut despite being poorly received by critics and fans. SNES has finally been dethroned - the world is a little darker.
