@gilgames I made some chore purpose pull requests last week. I'm currently working on the merge of the BULL mod. This will be done by the end of the week IMO.
Is there any chance you'd be willing to change the game timeline to
3 years/turn 500-950 (150 turns)
2 years/turn 950-1700 (375 turns)
16 months/turn 1700-1800 (75 turns)
This had been discussed previously back when Absinthe was still here, and I did it in my own copy of original RFCE, but I no longer am sure how to edit turn lengths since the python file with turn to year correspondences is gone
I've tested it, and this works better than the other proposal (3 y/t 500-900, 2 y/t 900-1700, 1 y/t 1700-1800), which was too long, or the current timeline which is too compressed.
Assuming you still want to add different speeds
Then for epic, it could be
2 years/turn 500-900 (200 turns)
16 months/turn 900-1700 (600 turns)
1 year/turn 1700-1800 (100 turns)
And for marathon
1 year/turn 500-900 (400 turns)
8 months/turn 900-1700 (1200 turns)
6 months/turn (1700-1800 (200 turns)
