Your favorite indie game?

Bastion, no questions asked.

Bastion. But I don't play much indie games.

Audiosurf

Trine games are my only indies, they are good.. Audiosurf looks quite fun, but I don't own it.

so far, Space Pirates and Zombies (SPAZ) is the indie i've had most fun with

The Binding of Isaac.

Penumbra series.

The Binding of Isaac and Plants vs Zombies :D

Insanely twisted shadow planet

Stacking

Top 10: Bastion, Lone Survivor, Defense Grid, Unepic, Trine, Really Big Sky, Insanely Twisted Shadow Planet, Dungeon Defenders, Slydris, Black Market.

If I had to pick one as the favorite, I'd probably pick Trine. I had no expectations when i got it, and it was just so. much. fun. :)

Special mention: Lunnye Devitsy because of the awesomely beautiful soundtrack

When it gets released, Starbound (do want), at the moment, Cave Story+.

Kerbal Space Program and Starfarer

Super Meat Boy and Lone Survivor , both awesome :)

Go for BRAID without moments hesitation. You wont regret it.

Legend of Grimrock !! tho bastion is nice too :P

Bastion, Braid, Night Sky, Cave Story +, Overgrowth, Project Zomboid, Dustforce, Eufloria, Machinarium, etc...
