Personally, I prefer Aurora and Distant Worlds: Universe. Paradox games are fantastic but these are Dwarf Fortress-level detail (if you’re into that sort of thing).
Is this that VB game that got eventually rebooted(?) in C#, that's full of annoying little glitches[0] that would be trivial to fix if the author wasn't aggressively against any and all kinds of modding?
I'm definitely looking for a 4X equivalent of Dwarf Fortress. Stellaris ain't it - I like it, but it gets too repetitive after first longer game, because the mechanics is just rock-paper-scissors with a hundred thousand numerical modifiers that have little qualitative impact on gameplay.

Like some number handling within the game being locale-dependent, so that unless you set your system locale to en_GB, it might behave unpredictably.
