If anyone's interested, the UK version (which I think should work on US PCs) is £14.99 on Amazon.co.uk. That translates to about $22 or something. I know it's only useful to some. It would be useful to me, but I want it on Steam, not a physical copy! (I'm in the UK until the 15th.) Wish Steam would copy Amazon's UK price (or even the Amazon US one).
