This game would be so good if they had made a slightly different business idea and didn't decide to go full greed. And yes I mean GREED!!!! To unlock all content in the game you have to shell out a substantial amount of money. You cannot grind around this as it is physically not possible to get the workers any other way. The game also throws a £10 monthly subscription at you (which I purchased) thinking that getting this would unlock all available content for me and guess what it doesn't. Greed!
