What is your favorite game you got from a bundle?

Probably Braid, though I just finished Thomas Was Alone from the current humble bundle and I really loved that game.

Blackwell Deception and To The Moon. I haven't finished Alan Wake American Nightmare yet but I'm enjoying it.
I have yet to play Hotline Miami

It'll probably be Brutal Legend, when I get some time to actually play it.

As for a $1 bundle, it has to be Alan Wake CE, no question.

By current measures, Binding of Isaac. But there are a lot of bundle games I have yet to play.

Postal 2 :)

Saints Row: The Third from the Humble THQ Bundle =P

If we're not counting that bundle then probably Super Hexagon from the Humble Android Bundle 5

Crusader Kings 2, if you count insanely good Amazon bundles.

Anodyne, if you don't.

Revenge of the Titans, Limbo :D

Bastion and Beat Hazard are both right at the top of my list of favorite games I own on Steam, but I got both separately before getting extra copies from bundles. World of Goo is probably my favorite one that was introduced to me by a bundle.

Saints Row: The Third.

atom zombie smasher

Braid and World of Goo.

Defense Grid

Machinarium. I'm not 100% on whether it was in a bundle or I bought it on Steam... not sure...

Hard to say, so many choices to pick from, maybe Sol Survivor, Waking Mars, or Botanicula, I've gotten so many bundles though it's hard to keep track of what I've bought in a bundle :P

VVVVVV

Super Meat Boy and Darksiders II

Alan Wake D:

also blades of time now in bundle, good game but i got it before

So many to choose from, but Blackwell Deception is up there very high and the Groupees Wadjet Eye bundle was filled with some gems.
Also Legend of Grimrock, Saints Row 3, Machinarium, Amnesia, Anodyne.

Braid and Super Meat Boy. Bastion is great, got it before it was bundled though.

If I have to choose 1 game , then it is "Dungeons of Dredmor"

Company of Heroes during the THQ Bundle

BIT.TRIP RUNNER

I only buy them, I don't play them.
