I don't have a good feeling about this delay.
Just from the previews I read back in the fall of 2019, every preview seemed to emphasize the same points about your crew developing alcohol problems or possibly falling in love with rivals and catching VD - which would make them lose their mind, etc. Every time I read this and thought about random personal problems with your crew as a game mechanic, it just sounded like something that would get stale pretty quickly.
For me, this game would have had to have had a really compelling turn-based strategy component overlayed by an interesting economic/organized crime sim that didn't involve too much micromanagement in order to keep things going. It might be too much to ask (i.e. the turn-based strategy and high level economic sim might just be too ambitious), as this could easily become one of those games that has dozens of tedious micro-level tasks to cover in each turn.
Here's hoping I'm completely wrong though - as I would love to have a compelling new organized crime game set in 1920s Chicago!
