Worst. AIs. Ever.
Unless you like opponents who consistent roll 7s and steal from you, I would pass on this app. When theyre not rolling 7s -- usually when you have 8 or more cards, rarely when they do -- the NPCs tend to focus on building the largest army. So, again, be prepared to be give up lots of resources to the NPCs.
The NPCs also pester you with the lamest trade proposals and reject your more reasonable ones. They also trade with one another more than with you.
Finally, the graphics are annoying and time-consuming. If you select "turbo," its STILL slow.
Settlers of Catan is a great board game, but this is very frustrating.
