Wii-- Red Steel 2. Very fun and satisfying game. Recommended for any Wii owner, even if you didn't like the first game. In fact, especially if you didn't like the first game. It's what Red Steel 1 should have been all along, and the MotionPlus device (required for it, but optionally included with it for $10 more) makes all the difference in the world.
Sega Saturn-- DonPachi. No fucking clue why, when it's one of the most lackluster shoot-em-ups on the system... Ah well, every time I play it, I learn to appreciate the better Saturn shooters even more, such as its vastly-improved sequel, DoDonPachi. It's like watching George A. Romero's
Return of the Living Dead, then watching any other zombie movie.
ROBOT UNICORN ATTACK!!!
it's what flash games were invented for.
Yep. That and Nanaca Crash. (highly recommended if by some odd chance you haven't played it yet. The game's ancient, but a goddamn classic.)
