How many creatures and on how many territories? When did you build the castle?:)
I just can't forget my 7 creatures with 1 each.

There are many creatures, maybe 10-12, somewhere on 40-50% of the map. I took the castle at the end of the third week, without angel creatures. There were three minimums, but I didn't take two, just checked them). I simply gathered 3+3+3+4 on the second turn and took a Utopia tier 3 with a Knight on turn 131. If I hadn't been building a teleportation tower for a week and a half, I could have done it faster.
Actually, I've never gathered more than 16-18 angels and this is a sample of two hundred games.
