LoZ: Wind Waker HD
Just picked up Shovel Knight, and I'm loving the hell out of it. I love the
NES design inspirations--I'm a hobbyist pixel artist, and this game is making me want to pick up the NES palette again. Likewise, the gameplay is brilliant thus far.
Freedom Planet is a neat little spiritual successor to oldschool Sonic games, and I'm enjoying that so far as well. There's somewhat annoying voice acting, but you can skip that by playing the levels end-to-end in the 'classic' mode. I like the health system in this game better than the rings in Sonic, and it's cool to see the game headed up by a trio of female characters.
As my partner pointed out to me, I've picked up an HD console and an HDTV just so that I can play new games that look old... (Not with Zelda, though! That's an old game that looks new.)
