You have stated its turn based, if that is how its played then no thankyou. I dislike turn based games, since it feels restricting.

Well it's an economy game where the game get updated every 24h. It's not the traditional Online Text based game, where you have to pointlessly spend your daily points on activities. For me personally it's an amazing real world economy simulation. Developers are even hosting training events for MBA students as it's so realistic
