I don't want it to go past 2300, and I don't want an overarching "ending" to the series. If the last game is a prequel (pre-Fallout 1, post-Fallout 1/pre-Fallout2, etc.) I'd be perfectly happy with that as long as the last game is a good game. If they never go back in time, I sincerely hope that it stays between 2281-2300, it just gets to the point where chaos is too rare.
Chaos is never rare, no matter the day of age or country in control. proof is in the history book.
Sure now a days we can walk outside without a fire gecko pouncing at us, but a random dog from nowhere could bite your hand like it did me.
And sure there aren't any raiders [censored], stealing or getting drugged up in a slum... oh wait! there is! How exciting.
No offense. It's just that if war never changes then it also never ends.
