I guess that depends on how narrowly you define “genre.” It’s a pretty good sandbox RPG, and it’ll get even better with community mods. If that’s what you’re looking for, it’s great and way better than pretty much anything else.
But if you broaden it a bit, it has a mediocre story, mediocre combat, and mediocre exploration. So compared to other RPGs, it’s really not special.
So I’d give it a B grade. It gets Cs in many areas, but the sandbox is good enough to pull it up to a B. To get to A, it needs to excel at something, like exploration (e.g. do more with the ship in space) or economy (e.g. invest in trade routes and impact the cost of goods by flooding the market). But it doesn’t really excel at anything, it’s basically the same formula they’ve had in the past with a different setting.
It’s still a good game, it just doesn’t stand out in any particular way. For everything it does, another game does it better, and it really needs to be the best at something to get an A from me.
