Matchmaking is quite fast for me. Much faster than other games I've played. There's a learning curve for figuring out all the actions but its well worth it. The UI sometimes feels too "minimal," I definitely could not figure out the trading screen for a while and it wasn't clear where you were able to click. The scrolls are a fair way of giving users a preview of the game before buying it.
I think the ratings are a little bit biased or maybe the developers fixed things in the past 5 months. This is definitely not a bad game by any means and feels well developed. It just needs a lot more polishing.
@DarkRider I play on PlayCatan if I want to have fun. I don't have to play much on CU to see how broken it is. One game can show that there are a lot of ways to make the UI go crazy. Trade screen can freeze under specific conditions, some actions take a lot of time etc. Seems like the developers have not had any experience with Unity before making this game. Why should anyone waste their time playing on CU when PlayCatan is 100 times better?
I think the @Administrator just does not care anymore. He is the buffer between the public and the people who actually make decisions. None of the complaints ever reach the right people through this forum. Have to use twitter, Facebook and other means of communication to complain about the shortcomings of this "game development".
