some people didn't like it because the combat takes a while to wrap your head around since its so different from other turn based strategy systems, once I figured it out I really started to enjoy it. I appreciated the extents they went to to eliminate RNG entirely, that shit drives me up the wall in games like XCOM.
The story is really great as well, shows just how awful it is to be a refugee. You have to keep moving or you'll die but wherever you go no one wants to help you because "oh great more refugees." Rather puts things in perspective considering all the refugee crises going on in Europe and Asia atm.
