Most important:
This game is well-made, has a lot of fun hidden and extra features, and is actually quite strategic. You can spend a lot of cash easily on this game and offers are always available, or you can figure out a strategy and always have available resources. It took me a little bit to figure this out and I likely will still spend on money here and there.
Unfortunately customer support for this game is abysmal. I’ve worked in tech support and customer support, and the answers they give are basically, this is how the game is, enjoy! They don’t actually read what you write or explain their answers. It is possible there is a language barrier, but often replies are very snarky and even condescending and rude. I have used the link from here to email support and in-game support (which is what is recommended) and both are very poor. The email was slightly better but not by much, and I only used it once so it’s not a great comparison.
Beware if you play this game and something isn’t right or you have a glitch, they won’t ever make it right, or help out. BUT, the game is very fun, engaging, always new, and so well-designed. It is very addictive. I would recommend this game as a fun one as long as players are aware of basically zero help from customer support.
