What is your favorite game you got from a bundle?

Torchlight. It's the one I've put most hours into anyway.

Not sure. Too many of them in bundles. And I even missed some Royales and most of the Stars and...

Torchlight, which has 21 hours of playtime.

Beat Hazard. I just love that game, and it ran fine on my netbook :3

There's even a version for android now too!

Dungeon Defenders, I never thought I'd like it.

BIT.TRIP Runner. The game is entertaining and very addictive.

Psychonauts and Super Meat Boy.

binding of issac and bastion

To the Moon

Limbo.

Amnesia by far, HIBV

Mine has to be Binding of Isaac, awesome game.
Picked it up in the Humble Indie Bundle 7

Hotline Miami.. wanted forever on discount finally got it via a bundle :D

Bastion

Amnesia, Saints row the third and Serious sam 3.

Well recently, I really enjoyed Thomas Was Alone... Only took me about 3.5 hours to 100% it, but it was definitely an enjoyable experience. There are 100 levels or so, and they constantly add new mechanics throughout each of the 10 chapters, and the voice acting is wonderful. So wonderful in fact, that it honestly makes you care about colored rectangles. xD

bastion, trine, aquaria, world of goo(android), max and the magic marker, closure(although it was bundled I didn't get it from there, I got it here from somebody else's bundle so it still counts right?), supercrossfire, and first impressions say also thomas was alone

off the top of my head. i'm sure some others came from bundles too

can't really decide which(but some of these i like more than others) so just listed top few

Saint Row 3 .

I've been loving Psychonauts, though I haven't gotten that far in it. After that, probably Bastion as well, though I already had played the iOs port.

honestly... Fate of the World... something about that game just keeps bringing me back for more punishment.

Bioshock Infinite from The Greenlight Bundle

I'm too lazy to completely check, but it's pretty much Amnesia: The Dark Descent. I forgot what bundle it was from.

Of the ones I've played so far: Blackwell Deception. Loved all the Blackwell games

Torchlight

Saints Row 3, and World of Goo(I played it on my mobile a lot, even if not on steam)
