The book i developed was built around the idea videogames can be built off of it.
The main idea would be to make a battlefront type game, with many sides. That have no reset, ships are continued to upgrade. You would command an asteroid mine, which you keep upgrading and building, you build fleets. As opposed to cookie cutter ships and bases, its less gimicky. You would have trade, the best part if your fleets and asteroid mine is destroyed… you start on the planet, trying to fight back into space. Probably with 5 to 10 people fighting on the surface, and looking for ore. Which larger groups will try destroying and looting the bodies. Getting rid of restarts would be a healthy thing, the disadvantage of not fighting would be technology would pass you by.
An example have cities, asteroid mines, and outposts that are computer controlled trade centers, that can be destroyed, and rebuilt. Custom armor paint jobs, similar to clone wars commander and captain armor. As opposed to building a million pieces of equipment, use an unlimited dungeons and dragon system of take an item, and allow endless upgrades to the item. So a hand gun might be 6 bullet magazines, 5hp damage, 25% accuracy, fires 1 second per round, 5% jamming chance, 1% self cleaning. Have 30 seconds to reload empty magazines. What then happens is you can buy another magazine, next maybe upgrade the gun barrel, improving accuracy 5%. Than you upgrade gun mechanics, like the trigger, springs, and will increase fire rate to .8 seconds per round. So extrapolated out, if you have 20 bridge officers, against 20 marines, and they both have hand guns. If the bridge officers have upgraded guns, they likely will win.
