I have played Fallen Enchantress / Fallen Enchantress: Legendary Heroes (from back in 2013) and I thought it had a lot of potential, I liked the tactical battles and hero focus.
The economy system seems a bit boring (although it's not usual for 4X games to have relatively primitive economy systems) and there were some seemingly minor, but extremely annoying things about the UI/UX.
I guess I should pick this up and see how they've refined things over the past 10+ years.
