I was thinking, maybe it would be cool and somewhat practical to set up a quick building challenge. I don't know yet the exact conditions. But lets say you make a new portal in new lands and with me at least, it is usually the case i have to set up something quickly again.
A quick building that is practical or for a very specific limited purpose that is set up as fast as possible while still achieving some aesthetic standard. So you get this kind of build time and limited resources and make the most out of it.
This might yield some interesting tips and tricks on how to build certain things fast and efficient. What do you think? Examples would be: a minimal house of wood(maybe some grades of this minimal house in minutes like 5 min, 15 min or 30 min house), of stone. A minimal tower etc. Also i would not count the resource gathering only building time.
Let me know what you think.
