PC gamers have long held the upper hand over Mac gamers, but Valve hopes to extend an olive branch to with their announcement that their digital distribution platform Steam will soon make its way onto the Mac.  Following image slipups and a series of Mac gaming teasers, Valve plans to treat the Mac as a tier-1 platform, resulting in simultaneous gaming releases for both the Mac and PC.

Coming this April, Mac users can expect to get their hands on some of the best games Steam has to offer.  Among the first will be Left 4 Dead 2, Team Fortress 2, Counter-Strike, Portal, and Half-Life.  Towards the end of this year, the release of Portal 2 will represent thesteam beginning of the Mac's tier-1 support.  Further, users on either platform will experience the same multiplayer interaction, sharing servers and lobbies.  Owners of games downloaded through Steam will also be able to play on the other system for no extra costs.

Ultimately, this is some very big news for Mac users who have long been pushed to the back when it comes to game development.  As third-party developers take advantage of Steam's distribution to both major platforms, expect to see a whole lot more gaming on your Mac. You can bet come April Portal's taking top priority on my end. Which game are you most looking forward to?
