The plots will hold a 15 x 15 in theory and nothing larger. But a 15 x 15 is max secureds if memory serves. And if you have HS booster ya get a bit more storage, on any home you own.
Siege does not really have a LUNA like other shards, so our Luna is nowhere near as disgustingly overinflated pixel crack malls of billionares, sellin junk for over inflated prices, that make no sense any longer.
So I doubt seriously if our New Magincia will become another LUNAESQUE mess here, since we do not even have the same Luna mess, as other shards have, ie the ghetto of inflation.
Do not let anyone take the wind out of ye sails..
if ya really WANT a plot there, go buy some lotto tickets !
At worst, sell it if ya win,
to someone that maybe does wanna live on the island,
of misfit toys, hermits or castaways.
I really had NO intentions of even buying any lotto tickets for New Magincia.
Aside from lotto fever hitting me,
once I toured it all,
it looked to me like a perfect place/island,
for those whom reject the establishment
or whom reject the norm, to set up their new isolationistic sorta, homesteads !
So, I bought more tickets than I figured I ever would,
and still it wasn't very many tickets, even, that I bought.
