It's not a bad thing that the CEO is really enthusiastic about science and a little bit of that trickles into the game. No, it's not a college course. But it doesn't warrant sneering, that detail enriches the game and opens up possibilities. I'd much rather the CEO's passion for science be one of the project's guiding lights rather than, say - the CEO's need to be a filmmaker and have revenge on Hollywood for ignoring his vision of ripped off Niven space kitties.
Sometimes you just don't need to consult a geophysicist when you're designing a video game.
If you're reviving a popular series of space sims that are thoroughly drenched in Brabenesque geeking out, it better have a certain amount of Brabenesque geeking out to be a worthy followup to the first three games. If you're creating a scale 1:1 recreation of the galaxy and charging people for it, yeah - consult some scientists. More food for thought, more possibilities.
It's not hurting anybody or damaging the success of Pokemon, so let Braben be Braben. It is totally OCD in a good way and I'll keep chucking them $45 a season for it!
Doing a tiny bit to inspire an interest in astronomy in your audience isn't a bad thing. It's not like he's forcing us to eat oatmeal, it's science FICTION. We get to pew pew things.
I'm sure it drives some of the devs nuts, tho. Can you picture the behind the scenes arguments? Ha! I'd love to hear some of them open up about it.
