I think one of the smartest things about the writing, and the thing I respect most about it, is its use of expository dialogue, something I whine about pretty frequently. This game has a lot of exposition, more than most of its competition I'd wager, but it never feels like it. The game gives you a lot of information, but never something irrelevant that you wouldn't need or want to know in the moment, and it's always framed in a way that the goofball protagonist can understand. It makes the setting feel more natural and accessible, and eases the player into the big cosmic mystery at play. And because it's framed for an actual idiot to understand, and certain details are obfuscated for his benefit, it gives flexibility to future writing, not everything needs to be set in stone as long as it's logically consistent with what's previously been said.
It's way too often that I see a game shove paragraph after paragraph down the reader's throat, frontloading every piece of information possible into one big, ugly, hard to swallow chunk, and I can't fully express my relief to see it done right here.
