I was really glad Wizorb was added, been wanting to play that one (already had picked up the bundle). Only tried shatter so far but really liked it. These bundles have provided me a shameful backlog of games in my steam library!
I hear you. I've got like a Steam collection addiction.
Torchlight is pretty fun, glad to say I won't have to buy Diablo 3 ever. SPAZ seems cool, but I read it was comparable to Star Control, I got my hopes up.
I had Bit.TRIP Runner already, but I just can't play it. My eyes cross and I start drooling.
