Loved this! My new favorite leader. Lots of flexibility and fun gadgets and art. Didn't even notice about the mementos, so I'll have to try again and use those.
My one reservation is that the science victory screen kept crashing the game. I had my banker on standby, clicked for the economic victory and that ran just fine.
main thought is it could be caused by the game attempting to assign XP rewards for the victory, but running into an error because it's not a recognised leader. strange it doesn't have this problem for any other achievements, era transitions, or the economic victory though.
i'll look into this further.
thank you for the review!
