Inspiring Business Sim
Allows you to establish and operate most of the details of a simulated business in a realistic market.
There are many approaches to this game for you to choose.
You can simply open up a chain of retail stores and sell other companies' products and/or import them. Wide variety of goods to choose from.
Another approach is to just be a primary producer in manufacturing, mining, lumbering etc to sell off to companies demanding your produce.
A great feature is the realistic stock market dynamics featured in the game. You can make a large portion of your wealth through the trading of stocks of your competitors. Since you normally start with $50m in the game, your returns can be limitless similar to investment strategies used to real stock markets.
Ofcourse, you can be a 'jack of all trades' and take ownership from primary production and product innovation/invention all the way up to sales to the end consumer.
Marketing, product research, mergers & takeovers, property investment, hiring and firing your executives, it's all included. The graphics are 2D and nothing special, but considering when this title was released, and the fact that it's a business sim, this isn't really a major downside.
Gameplay is reasonably simple although you should give it at least 1-2 hours to learn how to thoroughly play this game.
You can pick up this title in bargain bins probably for less than $10 these days - EXCELLENT value for the price provided that you're looking for this sort of challenge in a game.
