If you earn XP for only existing in a game, what is the point of even participating? Students can just stand there to earn skins, and they wouldn’t answer questions as a result. I understand if you want students to earn XP more often, but you could add Dev access only trigger zones or something to earn XP. Maybe adding on to the idea of Verified Creators. You could give access to XP zones to them.
XP is earned over time but you have to answer questions, so it’s really based off of how much you know about the subject.
Also, this off topic. I don’t like minimodding, but I just wanted you to know.
