Empire should make a theatre so that people could perform plays as a way of getting rupees. if you wanted to watch you could pay to see it and pay extra for a programme or vip seating, just an idea if you like it, great Lewis
The whole idea of theatres in Minecraft, official or player-made, doesn't really work. It's essentially a cast of people walking out in a certain sequence, typing something into local chat, maybe carrying on a conversation with another cast member or jumping a bit, and hoping that their audience, who are sitting at a computer looking at all this, will be entertained.
Well, I have thought of this, and then I made my own Restraunt and Theater... Skyfall Cafe & Theater-smp1,1103. I think that you should just make one in your own lot though. It will bring more business, trust me.
Or with the arrival of fireworks, you could run a fireworks show with performers doing certain things :/
I also think that a theater could add visual appeal to a place. Even if no one really used it you could have it there for show.
