To be fair, you can have two products that uses different technologies but have a similar UI/UX, and in a way BlueSky is more similar to Twitter than to Mastodon, UI/UX-wise.
And to be honest it's a good thing: many non-tech friends were a bit confused about Mastodon, where you have to understand parts of the technology behind to do basic things (like follow someone from another instance, IIRC). BlueSky is (currently) a bit more friendly UI/UX-wise. I don't know how that will evolve with more instances, though. I also found that discovering people was easier, but YMMV.
If I'm not mistaken, Diablo 2 Resurrected is not a 20 year old game, since it is a remaster of the original Diablo 2. It has been released ~two years ago.(21/08/2021)
Steam reviews seem to highlight documentation and development issues! It is sad, the tool seems to be fine. Reminds me of aseprite (which is more 2d): https://www.aseprite.org/
I've been using a Polyend Tracker for ~6 months and it's been such a fun experience. I'm by no means someone old enough to have been using trackers back then but the Polyend Tracker is has a really thought out interface enabling rapid prototyping as well as whole song production on it.
