I've checked out the demo for corporate machine by Stardock
www.stardock.com. It's the sequel to the game
Entrepreneur, it looks very similar but there are some improvements in the interface and you have more access to information (a feature sorely missed in the original).
All in all it's a pretty enjoyable business game. In the demo you start at the beginning of the computer industry and have to gain a 65% marketshare. You can improve your product by research, marketing campaigns etc and building various production sites through the world. The AI is pretty good, it's easy to win at the lowest level. But you'll have a fight on your hand at the higher ones, even more when you play with 3 computer opponents or higher.
If you like business simulations with some decent AI, try TCM. It's one of the best business sims on the market these days.
