I mean I was actually impressed how I got excited about the new features of the royalty DLC.
Mechanoid bases? Can't remember a good mod for that.
Quests? Yeah I mean there are mods that events/quests but not the ones that are added by the DLC. The hosting quests especially have nothing to do with the hopistality mod and I am particularly hyped about the construction quests.
New way to end the game? We had the one from rimgenetics and kind of save our ship 2 I think, this is another one that is achievable in a completely different way, that's interesting damn.
New tech level that mixes old tech and futuristic tech? Find me one good mod that has this retrofuturistic theme, because I don't remember seeing it. I've seen medieval mods, glittertech mods, dozens of other glittertech/spacer level tech but steampunk or whatever type of punk this tech is, nope.
Pyschic powers? I know only one mod that does that, it's been released in november of 2019 and hasn't gotten a single update since. This DLC hasn't been made in a month or two, by the time Psychic awakening got released the devs were probably way too invested to scrap the idea just because "there's a mod that does this and that seems to have been released and abandonned immediately afterwards since the dev of the mod sort of retired".
Royal Titles? I guess colony leadership kind of added a system that made one of your pawns a leader but it wasn't all that complex and not a massively popular mod either.
The one complaint I could agree with is that listing new music as a new feature is a bit meh but well music composers aren't free either so it's fair game by my standards.
I don't agree with people complaining about the price for various reasons.
But I honestly believe that people who complain about Ludeon Studios just ripping off content made by mod creators are just next level delusional individuals who have found no other way to justify their price complaints.
