Apple CEO Tim Cook has been spotted at the headquarters of the popular game developer Valve. Valve is the company behind the gaming store, Steam, as well as popular games like Portal and Half Life. While there was no official word on what this visit means, it does raise the prospect of a closer partnership and relationship between the two companies. This could end up filling the one market that Apple has traditionally had a hard time with, the Mac gaming market.
