Good indie games?

Braid is incredible, and one of my favorite games. Osmos is nice if you want something really casual. And although I haven't played it yet, I heard good things about Dear Esther (I just picked that up at a flash sale for $2.49)

Recettear,Trine, Binding of isaac, Defender's Quest, World of goo, Recettear, Recettear and did i mention Recettear ?

Limbo. Super Meat Boy. Torchlight 1.

Cave Story+

Dungeons of Dredmor or Bastion (especially Bastion because it is 50% off because of the Autumn Sale)

I bought Bastion, and I... loved it!! JUST BUY IT! Only 6,99$ now (13,99$ normal price)

World of Goo... and despite it's terrible review: Cargo: A Quest for Gravity

Rochard, Trine / Trine 2 and Limbo. My favorites so far, especially Rochard!

Torchlight, Trine. The best indie I ever played. Good one are also Braid, Machinarium, LIMBO or SuperMeatBoy.

Torchlight, Trine and Trine 2 for chilling :)
Limbo, Braid, Machinarium for good puzzle game
Super Meat Boy, Binding of Isaac, Basement Collection if you love platform that makes you maaad xD especially Meat Boy

On steam? Towns, Dungeons of Dredmor, Braid, Limbo, SuperMeatBoy, Hotline Miami.

Others - Neo Scavenger, Gnomoria, Recruits...Go have a look at Desura or check reviews on Indie Gamer Mag or sommat. ;)

Indie is the way to go.

ZenoClash is 99 cents rigth now, you can check the demo, and then decide (i like it)
also Torhligth and (or) Torchligth 2 if you like RPGs

Groupees Build a bundle 4!
9 games for 5.71 dollar

You should really try Recettear if you like tycoon or RPGgames. Or Anime. ^_^
Also I recommend the blackwell- games for any adventure-lover. They are really nice and oldschool.
Third I would buy ghostmaster, it has a funny gameplay.
