Firaxis does realize that we can tell the actual planets in the game are still randomly generated, right? All they did was slap a RL name on it. Maybe a couple of numeric variables like the star's approximate position and the local gravity. Maybe those details will affect gameplay, maybe they won't, but I guarantee you the entire thing is going to look dated as hell six months after launch when scientists start discovering even more new exoplanets, or details about the existing exoplanets that the game got wrong.
It's a good thing none of that 'realism' nonsense matters in a game about moving giant robots and spaceships around. I mean, I can respect that Civ as a brand has a legacy about being grounded in the real world, and Alpha Centari tried to keep to this tradition? But that's not the reason everybody remembers the games so fondly. We remember the games fondly because they were FUCKING GOOD GAMES. Alpha Centari had me fighting telepathic space-fungus, for crying out loud. I don't care what the name of the planet's local star is after that point. Why would anyone? That's not "realism," it's fan fiction.
Just make the game good, all right, Firaxis? Make. The game. Actually. Good. You used to know how to do that, back before every new video game needed to cost more than the actual space program. Nobody cares how "realistic" the names of the fake planets are. Just make the game good.
