You argued that people are performing mental gymnastics to show that 200 does not necessarily equal 200 years, because like me, they feel that the '200 years' means around 200 years and not exactly 200 years. I pointed out that during an interview with polygon after E3, Pete Hines mentioned that Fallout 4 was a sequel to fallout 3, thus events in FO4 should be after (and by more than 2 months, imo) FO3. This is also the interview that Pete Hines specified a 235 year old character over the interviewers 230 year old character. It suggests that 200 years is an approximation imo.
