PC gaming might not be for you, bro.

Get the current Humble Bundle if you haven't!

From my list what i would recommend:

Audiosurf
Borderlands
Clive Barker's Jericho
Dark Messiak: might and magic
Deus Ex: Human Revolution
Doom 3
Duke Nukem Forever
Half-Life's
Left 4 Dead's
Metro 2033 (a MUST)
Red Faction: Guerrilla and Armageddon
Saints Row 2
Space Pirates and Zombies
Titans Quest (with Immortal Throne)

Off the list i would say:
Mass Effect Tril
Darksiders 1-2
Fallout: New vegas
Skyrim
Magika
Terraria
Total War: Shogun 2
Warhammer 40,000: Space marine If you have any issues playing gamesi highly recommend SweetFX Shader Suite They are highly optimized and help your GPU work better with your CPU in a more balanced way.

Ys Oath in Felghana and Ys Origin.

Like everyone said wait for the winter sale. During the autumn sale I must've bought like 30 games, Zeno Clash was 90% off for R$1,65 (and it was great!), the Broken Sword Trilogy was 75% off I got it for less than R$4.

So wait for the sale and, very important, go on the search engine and look for games there for a reasonable price. There are dozens of games that are 75% off instead of the usual 50 that never show up on the main page, really search for things and you'll be surprised with the deals you'll find.

If I remember correctly about 55 games were over R$40 and over 1600 for under that price. It pretty much makes any game you want affordable and I'm sure the winter sale will be the same.

About the actual recommendations a bunch of stuff: Psychonauts (R$16,99), Dark Messiah of Might and Magic (R$16,99), Zeno Clash (R$16,99 but you saw the discount I got) like I said, also Analogue: a Hate Story (R$16,99) if you're into that style, Recettear (R$34,99) I loved the demo and am waiting for the sale to get it you should try it as well.

Another interesting one is Auditorium (R$11,99), you can play the demo on their website [url=]http://www.playauditorium.com/[/url]

Edit: Oh shit! How could I forget?! Get The Stanley Parable! It's free so you have no excuse and the same goes for everyone else here!

It's a Half-Life 2 mod but if you don't have the game don't fret, all you need is the Source SDK tools that you can download directly from your Steam client and the following mod:

It's a 15min game but it has 6 endings for you to see. It's amazing! You should try it.
