- What do you mean by that? - What do you mean by that... again?. I put in the description its a pipe but I didnt catch it well in the picture so thats why it looks ugly - Would you suggest sticking with another metal wall or using concretewall? - This is obvious. It's too dark and no fun to play on. People can't see anything, and flash lights aren't an option, because that way, only a small spot is illuminated and it's very annoying. Add more lights. - The pipe or whatever it is comes out of nowhere. It doesn't server a goal, only a cheap way to hang up some lights that look out of place. In real oil rigs, this isn't there. (Oilrigs require plenty of light for people to work properly on them) - That's up to you. You could keep the white-ish colour of the texture, make it concrete or keep it metal.
