700 npcs in the 'database' are not a problem,
on Graal2001 we normally have 1000-2000
(the railroads built with the railroad item are
saved on harddisk too but don't appear in the
npc-control).
Those npcs are different to npcs in levels
because they are saved all 60 minutes,
but they don't take more CPU time. So better
script the pigs better, then you can add many
of them. With better scripting I mean use the
command 'move', you could calculate the next move
each second and then do a move that last one second
(instead of calculating movement 10 times each
second and only changing the x/y).
