One of Steam for Mac’s touted features is its cross-compatibility with other platforms. Multiplayer games pit PC and Mac users against each other to truly see which platform has the better gamers. In addition, using the Steam Cloud, save games and multiplayer rankings are automatically uploaded and accessed. Once a game is purchased, it can be installed on multiple computers. Users can continue a game, started on your PC gaming rig, on their MacBook minutes later.
As a promotion for the launch, Valve is currently offering one of their most popular titles, Portal, for free download until May 24th. Portal topped critic’s best of the year lists in 2007, and has a sequel coming out later this year.
Steam is a free download from steampowered.com.
