I'm EpicCrafterer and I have just finished my 2 month project StairClimber 9000.
StairClimber is a 2-4 player game where players compete to reach the top of the stairs as quickly as possible. Each player receives a different class, in which they must do their best to kill the other players. Well, that's the general idea of it, the full rules are in the map!
I used a lot of redstone and scoreboard commands in this, so for the most part, everything is automated!
If you would like to feature this on youtube, feel free! Post here if you want to tell me that you're making a video.
