nitrogenhacks: The people at Dynaverse.net facebook page helped me resolve my problem, the game runs flawlessly on windows 10 at 60 fps!!! (orion pirates ran at 20-30 fps on win10, when it didnt crash)
So after my play testing I can give you a definitive answer:
Star Trek: Starfleet Command, the original title, if you have a machine that isn't running windows xp it is nigh impossible to get it running without it crashing.
Star Trek: Starfleet Command 2 Empires at War, The second installment in the starfleet series. This made several revisions over the original game, and unless you want the sfc1 campaign exclusives this is better. This game is a pain to get running on anything that isn't xp.
Star Trek: Starfleet Command 2 Orion Pirates, This is the standalone expansion to Empires at War (EAW), it removes the campaign but allows you to play as 8 different pirate cartels, it also adds several ships and some awesome weapons. This game is a pain to get running on anything that isn't xp.
Star Trek: Starfleet Command Community Edition, This is a remake of EAW, nothing has been removed from EAW, they added more missions and revamped the game engine so it uses more up to date software. Because the engine is upgraded it runs a lot better on modern computers, it also runs fine on windows 7, 8.1, 10. This doesn't play much different from empires at war. I would get this instead of empires at war because there are no downsides to this over eaw.
tldr; GET COMMUNITY EDITION (sfc:ce)
Is the Dynaverse market place the only place to buy most of those (apart from SFC1, which obviously is sold here on GOG)?
