Started playing earlier. 2-3 hours in now and it feels like I've barely even started. There was no difficulty select which I was initially worried about, because the demo was easy as hell, but I managed to Game Over twice on one of the first missions (mostly because I was being stupid). So I'd say it's safe to say some of the later missions are gonna be nice and challenging.
Last mission I just did took a good 30-40 minutes, could probably be alot faster but I was mostly trying to play it safe, so I'm guessing there's going to be plenty of hours to put into this. Missions don't appear to be repeatable but you can do repeatable skirmishes if you want to grind exp/money. Not that levels seem to make much difference so far, they've only added a very small amount of HP and a trait to my snipers (one got an occasional accuracy boost, the other got an accuracy boost when up ladders/roofs).
Also Vyse and Aika are on your squad from the start, fuck yeah.
