I have just successfully completed my first game of 0.86. I scored 3325 points.
I have had quite a few CTD with both 0.85 and 0.86 something that I did not have a problem with in v 0.77. These would occur at random moments.
However, this is now an enjoyable game. I felt I had to really work it, even towards the end.I had to balance my armies and heroes ensure that they were moving with purpose in order to prevent my enemies swamping me with hordes of soldiers.
I hope that diplomacy is expanded slightly, I miss the option to be able to extort money or other goods from weaker nations.
I did have weird problems, like caravans that started appearing, especially after re-loading a game from within a game. Also the outposts of other nations would remain after I captured a city whose ZOC included the outpost.
All in all this is becoming exactly what I had hoped for. Keep going guys it is getting there
