Sorry if you feel offended in any way.
I am fully aware people will always compare PP to Fireaxis Xcom franchise, just because its recent and they might not like to play retro games and are not old enough to experience them at their time (when they were top games).
We ll just leave subject alone. I am interested to hear by team which solution will they pick - one newer gens are accustomed to (that is Fireaxis Xcom/Xcom2) or one they have already developed in Xcom EU 1994 and Terror from deep. Or something of their own.
For anyone interested in old mechanics I have given my best to explain it here.
