Fair point. OK. So,
Can you name any famous parkour maps?
I can't, and I think if anyone could, I could. There was some drop thing, I guess... that's about it.
I disagree with one of the above comments about it needing to have awesome builds (Herb's mansion) because probably the most famous of all is Skyblock, which has almost nothing.
You cannot become famous by wishing to be famous.
The opinions of your maps will mostly be about gameplay. For me, it's 'just another parkour thing' and I am bored with those.
