Good cheap games on steam?

Dungeons of Dredmor.

L4D2 when it's on sale.

Here. Without any knowledge of what genres you're into, here's every answer imaginable.

Are you into platformers with a light-hearted story? If so I'd suggest psychonauts (€9,99)

Another fun and cheap game is Orcs Must Die! (€10,99) --> You should probably wait for weekend sales though.

for 15$ u should buy Trine 2

If you have people to play with I suggest Dungeon Defenders

Dust Force or Sonic Generations.

Thank you

Orcs must die(about 10,99euro,dunno in dollars),Bit trip Runner(forgot the price lol),Super meat boy(same as Btr lol) and....nothing else,but all of these are cheap.

Terraria is awesome game

+1 for Terraria

If you like hardcore games try Super Meat Boy

Also VVVVV is a very good indie gem :)

From what I played: Dungeon of Dredmor, The binding of Isaac, Dungeon Defender, Magicka.

Sequence (especially if you own a gamepad)

Bastion, Orcs Must Die!, The Binding of Isaac, Dungeon Defenders, Limbo, Beat Hazard (get complete).

(repeating some already mentioned)
Jamestown, Braid, Super Meat Boy, Orcs Must Die, Cave Story+, Defense Grid, Ben There Dan That/Time Gentlemen Please, Limbo, Blocks That Matter, Plants Vs. Zombies, RUSH
And lots of those have demos...

Terraria is shit, better buy Minecraft. + for Limbo, Blocks That Matter, Dustforce and from me: Rock of Ages, Trine, Gemini Rue, NightSky

There are so many games in this price category, it's really a matter of taste. Here are some good ones that I've played (not all on Steam): The Secret of Monkey Island: Special Edition, Defense Grid: The Awakening, Unreal Tournament 2004, Plants vs. Zombies, Serious Sam HD: The First Encounter, Peggle Deluxe, Ghost Master, Faerie Solitaire, Everyday Genius: SquareLogic, Cthulhu Saves the World, The Tiny Bang Story, Half-Life 2, Heroes of Might and Magic V, Trials 2: Second Edition.

Of course, sales make it easy to get other games at the $15 price.

I'm finding myself playing hours and hours of Audiosurf, which I got for a happy 3 coals back during the holiday sweepstakes so I don't imagine it could be very expensive now lol. You surf to your own music, woop! Youtube the gameplay of it to see what it's like :D.

i dont know how much in $ is 9£ but, for 9£ you can get dungeon defenders, it is one of my favorite games...

Dungeon Defenders.

Super Meat Boy.

If you think about trying to get all the achievements, you will spend many lonely nights crying yourself to sleep...

That is all.

Knights of the Old Republic

DONT FUCKING ASK QUESTIONS, BUY IT.

Bastion, Braid, Super Meat Boy, Terraria, VVVVVV
