Honestly I like Solasta's UI. I like the look of it just fine even if it's minimalist. But more importantly, the UI never interferes with my enjoyment of the game and as I've said before, it makes everything clear and easy to understand. I take one glance at the UI and I immediately understand all of my options. Could it look nicer? Obviously. But it's unobtrusive and makes playing the game easier. It does what it needs to do and everything else is just gravy. Honestly I wouldn't want them to change to the UI at all if it meant losing the streamlined simplicity they've gotten thus far.
