I have been working for 7 years on a 2D game that I has features they have announced. I don't know whether to feel happy for them to make the game of my dreams or disappointed for having to rethink my project
I mean Starfield took a lot from NMS, which took a lot from other craft-likes and space games. If your game has enough character and differents (ex. Being 2D like you said) it shouldn't matter.
