I don't get it. PS3 has the strongest lineup compared to what? Do you think there aren't four high quality games available on any other platform? Get real. Here's another Holiday lineup.
Mushroom Men: Rise of the Fungi
Black Sigil: Blade of the Exiled
Guitar Hero: On Tour -- Decades
Rune Factory 2: A Fantasy Harvest Moon
Tony Hawk's Motion Featuring Hue Pixel Painter
Prince of Persia: The Fallen King
That's only the unreleased stuff. Let me know how far I can go back for the rest of it, including Castlevania, Kirby, Viva Pinata, Bleach: Dark Souls and plenty of others.
