[Twan]

I build forts each time I have a province which may have decent ressources surrounded by my territory and neighbouring no other forts.

I build temples only in forts most of the time (except the first one, built as soon I can near my capitol to help my dominion and recruit some indie priests).

I often build labs without forts on the borders of my realm when I hope a long peace but don't really trust my neighbour ; I send most of my mages scripted for battle to fronteers, and they forge/research there. Also if I play an astral nation, labs on fronteers are cool for surprise gateway spells.
