I tried but ALL of the constructive suggestions were shot down. And they do not really reply to anyone else who makes the same suggestions I made a year ago anymore:
Lobby is still not implemented. You can not see how many people are online (how many are in game and how many are waiting to start a game, what kind of expansions people want to play).
The random maps are implemented in a way that makes unbalanced games. Using a spiral method for placing the number chits has been asked from quite many players. Also for the Ore for wool scenario - it is really easy to make a map randomizer to work but the administrator has always made a bullshit comment that it is hard to create a random map to fulfill the requirements of the scenario... Which is just stupid. Overall the random map generation is the core of Catan and the admin will constantly shut down any request about that.
The automatically-turn-ending timer, the trading UI not allowing counter-offers... These things are not going to change although they definitely change the way the game works compared to real-life games.
Since the administrator does not share any information about player numbers, it seems like there are not that many players playing the game. Which suggests that the matchmaker is not a very good idea for this game. Reasons: It tries to match players based on ELO... But since there aren't enough players, it matches players with very different ELOs together. And just the first 3 players who join the queue are placed in a game. No real "matchmaking" as such. Oh, did I mention that it is hard to create 4 player games? People just can not see the lobby. It is driving away more experienced gamers and paves the way for casual gaming.
And what about the games constantly crashing? There are so many issues with the game and they still decided to end early access phase. And the many things they introduced when coming out of early access had bugs in them (gold shop displaying wrong numbers, free expansion weekend not working).
I really want this thing to work. OR to make them cancel Catan Universe and roll back to PlayCatan and start over.
Technically speaking, Unity is a complete overkill for creating a board game implementation. 3D board is unnecessary. UI decisions are obviously meant for tablets and not for PC.
The attitude of admin indicates that PC gamers will not be listened to at all in the future. "Mobile is the future". This means casual gaming. And no real competitive scene.
