So, it would appear Halo Combat Evolved, 2, AND 3 are coming to steam + Plus other things

Also some other interesting entries I found:
Homefront 2, PAYDAY 2, Saints Row Episode 4, Saints Row IV, Black Prophecy(I thought it was dead :O)

Some things I noticed:

Clockwork Empires: by the people who made Dungeons of Dredmor!

Octodad: Dadliest Catch: hell yeah

Quantum Conundrum 2: didn't even know they were making a 2nd one

Xenonauts: strategy/turn-based, spiritual successor to UFO: Enemy Unknown (1994) apparently

Civilization V: Frankenstein: uh... what?

Fallout New Vegas Ultimate Placeholder/Fallout: New Vegas Beta Test: no clue, but...interesting.

Fez and King of Fighters games. If they release them, I'll be super happy. And I can't wait for Skullgirls release date, I hope it'll have crossplay. Well, looks like Steam will finally get more fighting games than SF games.

Aaaaaayyyyyyyaaauuuuueeeee? I mean - Halo 2 and 3 on PC?! Give it to me!

This... is actually good news. Wow.

Even more interesting

KoF

Yes YES YES YYESSS!

That being said I think this is fantastic. Halo CE is one of my favorites and I cant wait for Halo 3. I hope they do a good job on the port for Halo 3 though.

And it would really fuck things up for me if there was GFWL.

Don't really care about Halo 2 though. Heard it wasn't the greatest.

YEEEEEEAAAAAAAAAAHHHHHHHHHHHH

What am I reading?

Fun fact: Final Fantasy 7 and 8 have been in the registry for years now.

I might give Halo another try... maybe...

Halo 3 on PC? Whaaaaaaa

sounds cool

WTF! If this is true, I'm gonna jizz of the joy!

wow this is madness, I just logged on and wtf am I seeing lawl.

I want to see steam wallet trading to be reality. I need to sell my useless dota 2 items, I don't need them, but apparently they have some value

Also wow, really? I don't want to play them in PC

The files for Halo 3 have been there for years, so I wouldn't get hopes too high but it would be nice

No ODST? But that's the only game in the franchise I want...

There is an Official Halo 3 steam group.

can't wait to get it....

I'll shit all over the floor if they port combat evolved to mac

Seen this news posted all over net, and almost none include the listing site's disclaimer that no listing should be taken as a confirmation, that the Steam database has plenty of errors, and that there are other reasons why games might be listed in the database.

"Some people noticed things such as Halo 3 appearing in the database. Now, these Game Hub pages might very well be real/truthful, since I have no idea how they are made. Does Valve make these, or are they automatically made when a publisher enters/reserves a game?

In both cases, there are lots of errors in the Steam Database, some bigger than others, and this might just be one of them. Is it a placeholder and is Halo 3 actually on it's way to Steam? Or is it just another Steam Hub page that one of the publishers made for name-reserveration's sake? Or did some completely different developer need a cover to put a test version of his/her game under? Who knows?!

Everything you read on this site is subject to change, and until there's an official announcement from whomever is making whatever, it's not 100% truth. For all we know, at one point all the Halo's might have been coming to Steam, until they decided to go XBOX exclusive with Halo 3. We know just as much as you do. For now, let's just take the Game Hub information with a pinch ton of salt."

Trials Evolution Gold Edition :D

The Hobbit ?? there is a game about the hobbit? xD

Pirates Vikings and Knights This game is a mod or its a stand-alone game like chivalry?

Thanks ^^

I am also excited about xenonaughts! Pre-ordered already!
