Yes, it should be compatible. While I increase the difficulty of promotions by changing the goals, I don't alter the "difficulty" directly by slowing the progress bar like the MCCC settings do. It should be perfectly safe to use those settings in combination with my mod if you want an even harder experience.
Thanks for the confirmation! I love having a more difficult/realistic experience, so I am definitely going to try this mod out as I only now discovered it through Basemental. I wont jack up the difficulty at first and see how it goes with your default settings on my "Long" playthrough. Your mod only affects the career difficulty itself right and doesn't actually change skill up or University progress difficulty right?
