I see your logic in this, But I don't think Roblox will agree with this because mario has nothing to do with Roblox what so ever. @ David: This may not be the best thread, but please tell us your reason about the "No".

@OP It would be nice to have a contest partnered with Nintendo. But I just don't see it happening. On the grounds of that I'm not going to support. Sorry.
Well this won't happen. In the rules/policys of ROBLOX, they [ROBLOX] won't copy anything without permission. ROBLOX can get sued for this if they break a law.
