I find women's football boring to watch, but if I decide to get FM25. I may look at it. In reality, I may have looked at managing an international team, but if SI have removed that, it is even more unlikely. I also admit to not having bought 23 or 24, so very unlikely to get 25 as the game overall seems to be going nowhere new.
I imagine female players will be rated compared to each other and not against the men. Since a boys team beat a female National team in real life, ratings will surely have to be separated (apologise if this is already known. I haven't read the dev logs for awhile). I would be more likely to want to manage youth football than woman's football.
Still, I imagine many youtubers will play woman's football and that will help it gain traction in the game itself.
