Funny you should ask, I am actually playing Galaxy for the first time right now!
All I can say is that I really enjoyed Sunshine and will probably finish 100%ing it one day. With the patches I mentioned it feels about as modern as Galaxy (I suppose they are only five years apart). But better or worse? I can't yet say. I love the "Fludd" mechanic and find it really satisfying in 60fps.
And nothing of value was lost
EDIT: After reading the comments in this thread I think I should elaborate...
The only thing that makes Reddit not X or Facebook are their niche communities. For years, Reddit corporate has been moving to homogenize them and shove them all into a single algorithmic slop feed that auto-adjusts to what you linger on like Tiktok. /r/all and /r/popular are basically just endless slop feeds of bots reposing engagement bait for people with brain rot to look at while they poop. But having slop and topic-based communities in a single feed invites those brainrotted people to jump into any community they are not a member of and vomit all over it without learning the rules/culture/etc.
Honestly I think focusing on and prioritizing their myriad small communities and not the people who want slop feed is a smart move for user retention. I still won't go back there, but I think it's a smart move.
