Which version to get?

I'd like the 360 version for the achievement points and because its where I do most of my gaming (the living room) but does portal need mouselook?

thanks

anyone?

 

One of the reasons i've liked the hl series is they spend the time optimizing the code to run on as many pc setup's as possible. The pc version definately outshines the 360 with the added benefit of the mouse/keyboard controls. Ultimately depends if you want the achievments and if you plan on playing TF2 online with friends which isnt cross platform.
