Hey this is basically me pleading to the game gods for bethesda to, well basically seperate the JHE ending from the broken steel continuation by Using a menu to decide to continue the game but as an easter egg( not literally) so the john henry eden playthrough still matters and doesn't become a continuation of bs
Eg. Finish enclave side mq watch slides then box pops up "you have completed the mq and contamenated the purifier blah blah...would you like to play on on the cw? (this does not effect the story).

You might have better luck posting in the mod section. I highly doubt Beth is going to modify Fallout!
