I've actually gotten hooked on some old school games as of late. Gradius 3 on the Wii virtual console, and a really nice graphically remade version of R-Type on XBox 360. Both are ridiculously and frustratingly difficult, but addictive and fun as heck at the same time.
Also downloaded Magic The Gathering: Duels of the Planeswalkers for Xbox 360 last night, and am impressed thus far.
I'm looking forward to the Ghostbusters game, but will wait to borrow my friends copy.
