I never understand why the U.S. versions are always more expensive on Gogamer.com.
I think it's b/c most USA gamers would want to buy the USA version of the game b/c it's the USA version. Me, if it's the same game exactly in the USA as in the UK, as long as their ain't annoying activation stuff, I'll opt for either edition; whatever's cheaper for me.
Only in those rare instances, like when the UK Version has more uncensored content allowed than the USA version (usually, they are more lenient on nudity overseas on the rating boards than over here in the USA) -- i.e. see The Witcher and Fahrenheit (aka Indigo Prophecy) -- does Gogamer jack the price up higher on the UK Version b/c they know it's going to be sought after by USA gamers.
