I was so steamed about this as a teenager back when it happened - pretty sure it was one of the foundational reasons I started to consider building my own gaming PC once I got the money together.

As an adult, and with the hindsight of seeing how Valve has (generally) supported their games over the years, I can appreciate gaben's reasoning for cancelling it... though as someone gaming on the Mac, we were all kind of used to being second class citizens and bodging together mod support and whatever, so I still think they should've let it come out.

I would much rather we just eat the money we’ve spent so far than take money from Mac customers and shortchange them.”
