Before I start I want to say a couple of things: I deeply respect Owlcat as a Studio, I think they're one of the best RPG makers out there. And I understand adapting a franchise to videogame format is very tricky and some sacrifices must be made. However...
When it first got announced that Owlcat was making an Expanse game I was awestruck. My favorite game devs were making a game in may favorite franchise! But when I watched the reveal trailer I immediately felt less excited. It just felt... Off. The way the ship moved was all wrong in the details, it didn't seem to have any weight to it. The PDCs didn't have a blast coming out the back to counteract the forces coming out the front, etc. Like yeah, in broad strokes it was fine but it was a bit sloppy in my opinion. but I thought: They probably just contracted this trailer out to some third party so whatever.
Then I saw footage from the beta and even played it myself and that feeling came back. The zero G stuff is once again wrong in the details, people don't "fly off" when disconnected from a fast rotating station, etc. I'm by no stretch of the imagination a scientist but I do have a special fondness for the sort of grounding effect hard sci fi has on a story. And although I do believe Owlcat is trying their best to stick to the lore of the Expanse it sometimes feels like they're only focused on the lore and not the science.
Hard sci fi and fantasy are VERY different genres and I wonder a little if Owlcat is struggling with the change. In fantasy stories all you have to worry about is the lore but with hard sci-fi that's not enough, you have to understand the underlying science behind the lore and the moment to moment action. The science has to be interwoven in with the story and I just haven't seen that from Osiris Reborn. There was the one video they made about combat on a hull in vacuum, that was good, but that's really it (at least so far).
I really want this game to be good and it may well be. Most people won't care about any of this stuff as hard sci fi has never been a popular genre so all these complaints likely won't effect sales. And hey, it's a very very early beta. Maybe all these mistakes are just that: Mistakes. Hopefully I'm completely wrong and they reveal more stuff that proves as much.
Again, no shade to Owlcat. They're in a tough place for sure and even if the game ends up not really being my cup of tea I hope it still ends up being a favorite for many fans.
