Mario Galaxy 2, Red Steel 2, Metroid: Other M, Zelda Wii (most likely), The Grinder, Gladiator A.D., No More Heroes 2, Tatsunoko vs. Capcom, The Last Story, Xenoblade, Cosmic Walker, Endless Ocean 2, Monster Hunter Tri-, Fragile Dreams, Sky Crawlers: Innocent Aces, NBA Jam, Sonic & SEGA All-Stars Racing, Shiren the Wanderer, Calling, Sin & Punishment 2, Lego Harry Potter, Trauma Team, Transformers: War for Cybertron, Epic Mickey, and Star Wars: The Force Unleashed 2 all came to mind just as I gave it a quick thought.
