I see I began with A5 extra registered Wed, Dec 16, 2009. I'm old and slow, and not moving to a new system now. More Detail: I remember seeing seeing a demo [the offfice ?] and becoming very excited. I bought a copy of A4 or 5 from a 3rd party shipper, railway supply house. My interest has been developing 3D walkthroughs of the appearance of towns during our 'settlement era' of about a century ago. I've done a couple of town projects for local museums. The difficulty being that the museums have limited budgets, and developing hundreds of building models from old pictures is time consuming.
: well you get the idea. Museums usually want either the 'game'; or a walkthru I make with FRAPS.
Just continuing on building stuff from AUMs or looking at the contest demos.
