Nothing short of setting a firm foot forward this year, it looks like Sony's good to go with at least 20 exclusive games and they aren't afraid of pointing it out.
Sid Shuman of the PlayStation Blog notes a list of games set for release exclusively for the PS3. This doesn't include the plethora of third party titles.
"...Nearly every major PlayStation series is making an appearance in 2011 "” even Kratos is in on the action with his guest turn in the new Mortal Kombat," says Shuman. "Add third-party publisher PS3 exclusives and upcoming PSN games and upcoming PlayStation Move games and you've got a 2011 that's jam-packed with PS3-exclusive titles."
