No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $34.6K — a different platform, not this one.

Don Duality

You take on the role of a restaurant owner who just happens to be the Don of a mafia group. You will be giving orders to your gangsters, robbing people and collecting debts, stealing valuables and intimidating cops. However, you will also have to manage your restaurant - hire staff, advertise and try to avoid random events that will interfere with your operations. Will you be able to maintain balance between your businesses? How long will you last? Your restaurant will expand and improve. Buy extra tables to seat everyone who wants to visit your establishment. Advertise to increase popularity and invite as many people to your place as possible. But remember, the more people your restaurant attracts, the more staff will have to be hired to serve them. Most of your subordinates will be Gangsters. Send them on a variety of criminal activities. Rob banks, beat money out of debtors, intimidate cops. Be careful when discarding cards. Some of them are marked with a little bell. When such cards appear in your hand, the events get added up to the matching bell's progress bar. Once an event is triggered, it will seriously affect your business. At the beginning of each day you will have to consider the amount of money laundered through the restaurant. The richer you are, the more the police will be interested in your business. Once the police concern is maxed out, you will be arrested.
