I’ve had my eye on these two games for a long time and I think they’re impressive, since I’m in love with the whole space/galaxies theme, etc. I’ve already watched a bunch of videos but it’s getting harder and harder to choose between the two. If I could, I’d obviously just buy both, but they’re both really expensive. I live in Portugal and just Starfield alone is 50 euros. And it rarely goes on sale.
The flaw I noticed in Starfield is that it doesn’t show your ship landing on planets, whereas in No Man’s Sky it does:

Because of that, the choice gets really hard. Still, I’ve been watching a lot of videos of both. In No Man’s Sky there’s more of a focus on crafting stuff, collecting minerals, repairing your ship, etc.
And in Starfield it seems like you spend more time actually inside the ship.
