At this point of time (13.06.2021) Democracy 4 shows a nice progress over Democracy 3 with all additions. D4 is technically better, gives more info over the country under your control (for instance, disposable income breakdown). Hovewer, currently it is not optimized: game tends to crash sometimes (it happened 3 times for 10 hours for me) and is not very smooth, expecially when you try to hold pointer over a specific policy in order to find out it's influence over something else. I hope that a developer will improve the performance and stability of this game, and then it would be a great successor to D3
