This would be an out of the box approach to a game. Similar to the game “MMORPG Tycoon” (I recommend giving that game a google search).
Ideally, this game would start the player out at the late Modern time period in human history; at the time the telephone was invented. The player would have control over his/her local telephone company. Managing employees, deployment, equipment, pricing, etc, would all be controlled by the player. Research trees will split into subjects such as quality/reliability, major features, network efficiency, and business/economic research.
Eventually the player will be able to research cellular technologies (maybe even satellite technologies later on), and branch into a whole new world of business.
Just a thought I have had for a while. I can’t do much but I can make textures in Illustrator, and am handy with Photoshop.
