| I was supposed to get up and work this morning. Instead, I started GCII |

I laugh not in derision, but as one who has been there.
G.W., you don't need to connect to the net every time you load a saved game. You only need to sign in when starting a new game and when posting a score after you get the victory screen. I play with my laptop completely disconnected all the time.
I don't think I've ever seen a Stardock splash screen when completing a tech. I have occasionally seen a diplomacy screen flash on and off when I do things like open or close the colony manager and research screens, but that's about it.
In all respects, a Metaverse game is no different than a normal game. The only thing you have to do is sign in before and after the game.
