sry if som1 alrdy said ths but i didnt read it all.
what if ther were 3 types of houses that could be pre-made
like:
Hut: (one room, just a bead, and a cubord*) 10k
Small House: (one room, 2 beads, cubord*) 15k
store: (two rooms, 3 beads, cubord*, 5 selling spots) 25k
* = storage system AKA bank...
each could be placed after bought...that would reduce lagg...
limit each person to one of these itoms
no more than 1 of these itoms per 100 meters (or whatever) less of them
Can not be placed on repeated terrain
can put passwords on them
you could even make it so it just looks like a door frame. and when you walk into it you are teleported into the house...so that you wont have the lagg of a full house all the time...
