Great base game, but the programmers have not taken the time to implement proper A.I. Instead of the computer using strategy and cunning, it will manipulate the outcome so the robber is constantly thrown against you, rolls on your settlements are then thrown while robber occupied. As well, even when using the Stack dice roll option, if the computer can’t outthink you, it will devolve into ignoring the Stack rule and give your numbers less roll chance (I have screenshots proving this). Lastly, and the most obvious and annoying cheap tactic is that when playing against three A.I. opponents, one of them always seems to relegated itself as the sacrificial lamb in order to trade whatever the other two A.I. players need at any given time. Again, the base game is great, the different modes are super fun, but the unfair A.I. curbs the excitement. An important note- I’m not saying this out of frustration because I’m losing, I probably win 65%+ of the time, but I want to win against an A.I. with more fine-tuned programming. Lastly, I hope the devs aren’t saving all their programming efforts for the always online, less awesome version of Catan. PLEASE just perfect this one! Thank you!!
