I thought it was awesome! I could feel the Fallout nostalgia pulling me AND I got to imagine how it could look in a first person perspective! I know the teaser said nada about any camera views or anything, but DAMN, it could look good in first person!
Great job on choosing the music. Great job of incorporating all those tiny little details (Doctor's bag and the bottle of booze and stuff). Especially great job on the posters! Great job getting Ron's voice back in the gaming world (even though it might have just been taken from one of the previous games and not been re-recorded for the teaser). It might not have been worth the wait, but it was still a great experience seeing that teaser!
GOOD JOB, BETHESDA!
