Portal’s ending theme may well be one of the greatest video game songs ever created, and the duo behind it are also working on the sequel’s music. Jonathan Coulton:

I live and die by the niche, basically. I write all these geeky songs. It’s Internet people who keep me afloat for the most part. But then, suddenly there was this Portal thing, and it was a global phenomenon, and it reached all sorts of people that I wouldn’t have otherwise reached.

You can clearly see the handiwork of the team that previously developed the indie title Tag: The Power of Paint. It’s reassuring to see that student talent is not going unnoticed by larger studios.

Asked to name other developers that we’d see on Steam, Valve’s Newell demurred. But Steam’s popularity means that as Valve goes, so go other gamemakers. Steam on Mac means many more games on Mac.

To say that Steam is important for the viability of OS X as a gaming platform would be an understatement.

Excellent.

The inclusion of WebKit into Steam, and of OpenGL into Source gives us a lot of flexibility in how we move these technologies forward. We are treating the Mac as a tier-1 platform so all of our future games will release simultaneously on Windows, Mac, and the Xbox 360.

A formal announcement is likely during the 2010 Game Developers Conference, scheduled for March 9th to the 13th.

I’m betting we will hear about a Steam client for OS X then too.

This time in the form of mystery images sent to various gaming sites. I love when Valve does this kind of stuff.
