… for what?
If you mean “Can I build stuff for a challenge?” I would say yes. They’re literally…. the building blocks of building, not a fully existing piece on their own.
I guess we’d have to take your word that you didn’t have, say, a fully built Twilight already that you modified to suit the theme. But I think we’re all willing to do that.
EDIT: Ah, I see Lego was a challenge basically. Still, the above applies.
Also note that not nearly all mods can reply to these messages, so, delay. Sorry about that.
