I have an idea for Paccsu themself for when it comes to parts, but first I would like to say these are completely optional and I don't want to pressure Paccsu or have anybody pressure them to make this a thing but let me get started! (Fyi I edited this the post from another website which I made the comment from)
Basically, it's a set of Rockclaw parts that can be given as an optional reward from a quest giver that's fascinated by them, or you can learn to craft them, I would love to see Roxanne's reaction to Aida wearing it!
Maybe it could give some bonuses for what you wear, and as I said before in sets, so there could be a new augmentation that deals with arms and legs (if those aren't a thing already been awhile since I played the game,) then the actual costume/skin, or they can just come with the costume/skin, but these items, or just item.
But yeah, as I was saying cause of the special abilities the costume/skin I personally would have it be hard to get, or hard to craft, but if there's no special abilities, that's also fine by me, just means it'll probably be easier to get.
Other than that, thank you for your time, and I hope everything goes well for you Paccsu!
Edit: Also, woah 245 days since I purchased the game! and I must say, money well spent, after all the story and art style is just amazing! can't wait to see more!
