The 2nd question is multiple choice, but not the first.
A lot of games that don't have a playable demo still provide a benchmarking tool for PC users to test. Games that have been provided such a benchmark tool include titles such as Far Cry 2, Batman: Arkham Asylum, Just Cause 2, STALKER: Call of Pripyat, Final Fantasy: XIV, H.A.W.X., Devil May Cry 4 and Resident Evil 5.
So would you guys want such a benchmark tool for Skyrim and why? [Yes: I'm a benchmark geek.]
