I have safed most deads, not sure why. But here is how she died. Maybe you don’t want to see it. Citrinne’s death

Some modern games kind of expect your to use the rewind function like three houses. The unit spawn move on the same turn they spawn and it’s impossible to react to that if you don’t know them (some older games have this too) and in three houses they spawn just random in the map. But i think Engage is a good game for a ironman and i haven’t played the ironman on the hardest difficulty. But i agree with you that you have to think about more thing on modern days because every game has it’s own gimick. A lost a lot units on Fate because i haven’t thought about the pair up mechanik and needed to reset the map.

I’m sure my playstyle has changed a lot. I wasn’t that good in Fire Emblem at that time.
