I favor Divide et Impera than vanilla game because it's more historic, and this compilation is made for those who like slow-paced (campaign and combat both) games like me. It makes the game much more smooth without modifying the core setting of vanilla DEI.

• Slower economic development, no gold income from Mars, and higher building times and costs. It takes a long time to recover from war, and this is also true for the victors.
  
• Slower army recruitment.
  
• Slower combat speed, giving you plenty of reaction time to command your army in realistic mode.
  
• Friendly diplomatic environment, AI is more inclined to keep peace and make agreements with you, creating a satrapy may be more cost effective than direct rule.

Note: All Factions Playable and IA All Factions Playable are optional, you can turn them off if you don't want to play those minor factions (I really like playing as Kurēnaïkḗ in Grand Campaign, it was challenging for Ptolemaïkḕ to break the vassal agreement and declare war in the second turn).
Please put DEI 2,3,1 at the bottom of the list, and load the other mods in the order I listed them.
Thanks to Dresden, DEI team and related modders for their work.
