This is something I've been working on for a while. It's a pseudo-replica of the Bell Centre in Montreal. Whenever the Bruins play there I'm amazed by how steep the grandstands look, and how the spectators really seem on top of the action, so I'm trying to emulate that here.
The use for this, which I haven't divulged until now, is a concept I'm stealing from another game. The track is going to be called "Red Rover", and that's pretty much what it is. If I can ever get the motivation to finish up that scoreboard (taking animation donations!) I'll throw it all together. It's not a difficult thing to setup, but it should be a lot of fun.
