As far as I see, the AI in general and the gameplay was given a good work in this mod. Something that did surprise me even more than the great work is that many major factions just disappeared in profit to new factions and territories were reduced. It looks like the Byzantine Empire took a beating compared to Vanilla MIITW, same about the Holy Romans and Hungarians. Awesome mod, despite the fact that on some few point it does not seem like "Reduxed" but "Reduced"
