Valve have finally launched the Mac version of their popular gaming platform, Steam. I am expecting there to be a lot of happy Mac gamers
The library of games available for the Mac on launch are pretty large. It's currently listing at 60 games, but most of the games are from indie developers. Valve will release more games every Wednesday for the next few weeks. If you have a game already on the PC, you can just download it again on the Mac.
Also, up to 24th May, Valve is also giving out Portal for the all expensive price of free. Portal would be the first Valve developed game available on the Mac. I'll be waiting patiently when they bring out Team Fortress 2.
