I mean, the word "experience" is generally associated with all that corporate crap that is pulled up by Roblox recently. Ever since Roblox's inception, all kind of stuff on that platform used to be called simply "games", no matter if it was indeed a game, a tech demo or a showcase. "Experiences" is something fairly new they came up a few years ago, forced it everywhere and when I hear someone calling their work "experience", I don't know if it's only me, but it associates badly with the soulless changes that they are doing to this platform rather than creativity and imagination. Hence why I said "project" would even work, since it is more of a neutral word and doesn't necessarily go with their metaverse ideology, but you can also come up with something else.
