If you've ever played a 4x game before, it's not too hard to pick up. Stellaris is a fantastic game, and I've sunk quite a few hours into it.
With that said, sometimes they drop the ball on DLCs, and the late game gets bogged down/boring, so it's worth waiting for player reviews to come back before getting it.
Cool! Didn't know about it until now. I'm a big Stellaris nerd so this is interesting to me. But I'll usually wait until a game has proven itself before getting into it.
I saw a video about it yesterday - I think just because my youtube algorithm knows I like star trek. It looks fun! And it's not super expensive either.
