Irrelevant. Regardless of how you purchase it, the correct choice is to find a cracked copy online a few days later so you dont have to deal with the horrors of DRM disrupting your playing experience. Bit surprised Bethesda thought using Steam was a good idea, considering all of their past games have had heavily modded .exes created by users to fix the shit Bethesda didnt feel was worth their time. Sort of the attraction of their series.
