Mad games Tycoon is a simulation game like many others, except this time it is a game about making games. Yes it has been done before, so the real question becomes is it done well.
Short answer is yes, it has been. You start in your garage with a little money. You will build a few small rooms to start programming very basic games. With some more research money and time you can make bigger and better games.
Eventually you can make your own consoles and work with far more modern equipment, but you will have to earn your way there.
The game is fun and will require plenty of strategy. For fans of the genre its not bad. Its not much to look at however, tho most games of the type are not. Best wishes and may the gaming gods bring you glory.
