good game with multiplayer bugs

Overall, the game runs really well on single player mode. Multiplayer is not really stable.

First the good. Terraforming Mars is an awesome board game! The digital board is gorgeous and everything is intuitive if you’ve played the board game before. I really like the fact that bookkeeping is completely handled for you. The actions tab lets you see how many possible actions you or your opponent have left. This is all fantastic and an improvement over the physical board game.

With that said, multiplayer is deeply flawed due to bugs. The karma system is meaningless with the current bugs in place. Games will hang or you will get kicked out while a robot takes you actions. I’ve found that when this happens you can’t log back on and take control. If you forfeit you will lose karma, which keeps you from getting desirable matches going forward. Since the games are typically 75 to 90 minutes long even in digital mode, this is a big drawback. I haven’t dropped intentionally for the last few days but keep losing karma to these issues. In addition, I haven’t been able to figure out how you add a friend online. If the multiplayer issues were fixed, this would be 5 star app for sure. With these bugs, I can only give it 3 stars as multiplayer can be very frustrating to play. You can get a real match in here and there but my success rate has only been around 50%.

The latest update is a mess

It forced me to login again. I did so with the same login id I have always used for TM and now all my 1600+ achievements are gone as are all my completed matches and my ranking. I am back to being a new player. Great 🤬 I have 12 matches in progress but can't play any of them because they are not compatible with the new version. I could not complete them prior to updating because the game would not allow me to do anything except update. Again, great 🤬 I cannot delete those games, my only option is to resign from them which will affect my rating in a negative way as they are all ranked games, Great 🤬 I bought the new expansion and created a new game with three of my friends, but two of them are having such trouble just logging on that they have decided to quit playing the game, Great 🤬 Come on guys! Get your stuff together! I am changing my rating to 1 star until you do!

Good implementation needs a few things

First my brother and I have both played their actual board game so it was fairly easy for us to learn the digital version. As much as we loved it we couldn’t help but mention how difficult it’d be to learn the game because there were multiple things we had to search for in the Ui. However we were able to do everything we expected to through the game, it is a great digital version as it’s not lacking in any features we could find. My largest complaint is that it has no notification system so it is really only worthwhile to play if both players are going to play live. The online component gives the option to put time limits on turns but that doesn’t work great because you have to constantly go back into the game to check if it’s your turn. Even that wouldn’t be awful but it takes a good 15-30s to resume your game if you leave the app for ANY reason, even a switch to a respond or view a text message you have to sign back in and wait to reconnect. The game needs to implement notifications or have a way to see from the main menu whose turn it is. The only other flaw of the game is there is no undo, if you play a card or an action there is no way to back out of it even if it is still your turn. If those two issues were resolved it’d be a 5 star game
