I remember turn-by-turn being like a sergio leone film: it's so long and somewhat boring for almost nothing.
With a good music the mood is excellent, but only that.
Playing UFO-Extraterrestrials even remembered me that; it seems being like in old games.

So what, is there features making this game better if turn-by-turn?

Good turn based games or Bad turn based games are very subjective. I like this one. You may or may not. The music is kind of creepy, and helps to set the mood.

If you want some footage from the tactical maps, you can look up some let's play videos on youtube.
