As some already said, it would be nice to have an attack upgrade to kill monsters faster. Because monster, and more precisely bosses take a very long time to defeat. During this time you can miss some rare opportunity of investment and that is really frustrating.
I think I found a bug: if you use the magical protection card, IA won't attack you anymore. It can be broken if the AI uses the special caravan card (maybe isn't considered as an aggressive card)? And it's exactly the same with the ressources protection.
PS: Sorry if my English isn't that good, I'm French.
This game is amazing! Playing Men of the West and charge with a full squad of javelin trowers when squads size and preparation time are maxed is so powerfull!
How about having swimming pools and rafts in battles to enable players to place boats where there aren't any water and all other monkeys where there is water?
