I have changed a few things. On the scenario settings, the map is explored but not all visible. Also, I have added some rare resourses to the game for more realistic. On diplomacy relationship, I changed into all-peace mode, meaning you have to make diplomacy negotiations, and not being forced to alliance with Sun Quan.
After all, the game is tougher than before.
Remember: You need to have a medium to high cpu to have better performance. Don't forget to unzip the file into the right place that I have said before.
After you have finished playing the second or the third time, post some comments and ratings. Have fun!
