1). Single action Undo. Presently when you push Undo, it asks you if you want to undo your entire turn. If you say YES, you go all the way back to the start of your turn. The iOS app is friendlier in this regard in that you can undo only your last action, or any number of actions by hitting undo again. It is very handy when trying to avoid corruption, revolts, or simply trying to try out a number of different choices to optimize your turn.
2). Clickable OK button indicating "This is your LAST turn". I can't tell you the number of games where I would have played differently if I was sure it was my last turn. On the iOS app, you get a popup and you are obligated to click OK. You know with certainty that this is it, do what you can but don't bother collecting resources because you won't be able to use them.
3). Warnings. There are some warnings which comes up (ie. you are going to experience corruption!" with the option to submit anyway. That's great, sometimes losing 2 stone is worth getting that one perfect card out. However, the game will happily let you submit a turn even if you have a military tactics card in your hand, or in the common area, which is playable. What usually happens to me is I try out 4 or 5 different combinations, trying to optimize my MAs and CAs, and then finally submit only to realize I forgot to add the tactics card. I had added it on previous combos, but not the last one I actually submitted which was simply an oversight. Again, the iOS app has a pop-up asking if I want to use the MAs for that tactics card.
4). Maybe I just missed this, but how do you tell who first player is? It affects Age IV, if it hits when Player 1 starts their turn, that round is everyone's last turn. But if it hits when 2nd (or 3rd, 4th) player is starting their turn, everyone gets one additional turn. I never know who first player is because my player info is always in top right. I assume everyone else also sees their own info in top right. Is there a way to tell?
Thanks! Love the game, in my humble opinion, these suggestions if implemented, will make it even better!
