As everyone here most likely already knows, Steam for Mac is set to release tomorrow (May 12) and this is a huge turning point for gaming on the Mac. The success or failure of this business venture for Valve will determine how much Valve, other publishers, and Apple themselves support gaming on the Mac in the coming years. I urge everyone reading this to buy at least one Mac game through Steam on opening day, and to continue buying new games as they are released for Mac over the next few weeks. Valve will be watching the sales numbers to determine whether to continue Steam for Mac and how much effort to put into supporting and improving it. Publishers will be watching the sales numbers to determine whether to develop Mac versions of their new games, and how much effort they should spend on supporting and improving them. Apple will be watching the sales numbers to determine how important gaming is to their users and how much effort they should put into improving OpenGL drivers, offering higher-end GPUs, and doing other things to support gaming on the Mac. Let's all buy some games and give them some sales numbers that will make everyone stand up and take notice! The amount of Mac sales done through Steam in the next few months could make the difference between whether or not we'll all have to keep Boot Camp installed for the next 10 years. Buy some games through Steam tomorrow and spread the word to other Mac communities you frequent.
