I am very interested in this expansion and I am very willing to help. Though I think the southern expansion at ./warp thestrip is already doing the job great.
I really like the idea of a place for minigames. What I think would be great is a Spawn wall and roads branching out into Highways for roads. Also the idea for skyscrapers is being done by Bloxy at ./warp thestrip. All and all I like the idea mostly.
I like the idea of a spawn wall but it needs to be done in such a way that it's not problem viewing it so you don't feel trapped.
If it was cut at the furthest road so the road before the walkway to the museum.
The mini game area could be fun just need a space big enough and enough people participation.
