It was the June version 2023 version.
That in part is why I chose to play on H/H. I hadn't played medieval 2, especially not modified versions of the game in a long time.
And honestly, this version of the game is quite damn difficult. H is slightly too easy, but VH is very punishing. Took multiple restarts to develop a good "opening" strategy. For instance, on the second England playthrough, I found ignoring Scotland and Ireland made my life so much easier. Whilst in the first one, I lost the chance to beat up a weak and small france, and now every war is a horrible slog with a France spamming the "feudal" units at me.
Maybe that's a good level of balance though, I couldn't just jump in on VH and have success. I had to restart and develop a better plan.
EDIT: You may note some minor city/castle changes. I edited the strat a teeny bit, for instance I found giving france an extra castle early in their starting settlements gave them a much better chance at claiming those french lands. Ironically, I ended up reverting a lot of these changes as I ended up starting to understand a bit better the balance of the map. Just something to note.
