Dei Slow Simulator
This mod radically overhauls the essential data of DEI aiming to drastically slow down the game’s pace to achieve a more strategic, deep, and long-term campaign experience with a dynamic AI (24TPY, Tech 50–200 Turns, Building 10–25+ Turns, Recruitment 2/4/6/8 – Fully Compatible with AI Uses Population (WORLD SYSTEMS OVERHAUL).
It is a revision inspired by the excellent work done by the DEI team and many community members and aims to provide a slower and more strategic experience to the amazing work of Destroyer’s mod AI Uses Population.
This mod is only recommended for demanding users who are veterans of ROME 2 and want to participate in a more strategic, slow-paced campaign in which shaping the conditions of the empire and the diplomatic scene are more decisive in achieving victory than a quick war on the military field.
Recruitment, construction and technology times have been dramatically increased to match the times of 24 turns per year.
Also added elements of Profundis to make the campaign more demanding and difficult while all modifications to the behavior of the AI have been removed so that the mod is fully compatible with the AI Uses Population and More (WORLD SYSTEMS OVERHAUL SUBMOD). However, some elements to prier diplomacy may hinder (or complicate) the logic of AI Uses. It would be interesting to expand the possibilities of combining the two mods in the future
Changes
1. 24 Turns Per Year (24TPY): Τhis mod work seamlessly with existing 24TPY calendar fixes.
2. Technology Research: Research times heavily increased, from 50 to 200 turns, scaling by tier (e.g., early techs ~50 turns, imperial-era techs up to 200 turns).
3. Building Construction: Construction times start at a minimum of 10 turns, scaling up as follows:
Tier 1: 8-10 turns
Tier 2: 12-15 turns
Tier 3: 18-20 turns
Tier 4: 25+ turns
4. Recruitment Times: Different unit types have distinct recruitment times based on their role and quality:
Basic infantry / skirmishers: 2 turns
Elite infantry: 3 turns
Cavalry: 4 turns
Artillery / siege units: 5 turns
5. More army, navy, edict, and agent caps.
All changes apply equally to the player and all AI factions. The mod only modify the relevant timers and pacing tables. It does not interfere with or break the core AI decision-making logic of the AUP and DEI mods.
The mod also contains.
Cultural Tension – Events Roulette – Revamped city types – More specialized city types -Better Garrisons for prestigious cities – Big diplomatic penalty upon leader’s death – Historical Objectives for Rome.
COMPATIBILITY
This is a mod created primarily to play in combination with AI Uses Population and More (WORLD SYSTEMS OVERHAUL SUBMOD). Since upd 10/5/26 We have deleted all files related to cai diplomacy & campaign ai behaviour in order Dei slow simulator to better fit Ai uses population & more, you can be absolutely sure of an authentic AI behaviour if you simply place Ai uses population & more above Dei Slow Simulator.

HELP FOR THE MOD TIMES
For those who have trouble setting the 24tpy correctly in DEI, the surest solution I have found is relatively complicated but guaranteed. I configure the times in EditSF 1.2.0 (go ->campaing model ->campaing caledar change the value from 4 to 24). But for the seasonal changes to work correctly I also use the mod Calendar Fix for 12 TPY / 24 TPY. Calendar Fix must be on top of Dei Slow Simulator. The times will be 24 rounds per year and each month has an early season and a slow season.
Why I made this mod:
The improvements made by various mods such as DEI, TINY CITY and WORLD SYSTEMS OVERHAUL SUBMOD have brought ROME to an unprecedented level. However, I believe that there is a significant minority of players who would like a more "realistic" and "slow" mod that would give more depth to the strategy and time to shape the game. Elements such as the changes of the years, the duration of the recruitments, the restrictions on the creation of "barbarian empires", are indicative that would give DEI a whole new dimension.
