I prefer Galaxy 1 for its story and grander feel, but 2 is still one of my favorite games ever. Mass Effect 2 and Xenoblade would be my second and third picks. Shoutouts to Red Steel 2 for being such an amazing sword-fighting game with its motion-plus controls and to Goldeneye for managing to combine the old school elements of the N64 classic with the then-new school Call of Duty elements so well. It may be the best pure shooter on the Wii.
