Wow, I was only offline for a few hours:
Thanks for all your comments:
Eponick: The game itself will be shareware with a time limited demo avaliable. However, it will certainly be cheap. I'm thinking about 10GBP right now (maybe 15/20 for a boxed edition). At near the time of release we shall ask people to be beta testers and all those people will certainly get a free copy of the game.
There will also be a range of tools avaliable with the game for making your own maps which will be free downloads.
Theres a demo of a version from about 2/3 weeks ago on our website and we hope to release a new demo in the next couple of days for people to check out.
The Architect: We used CShop to make the individual buildings then built our own custom system for positioning them on a matrix.
PiratSS: My computers a 1.4Ghz 512Mb P3 with GF3. Your absolutely right about it being a little slow, as Damian said, to get a nice shot of the town I increased the viewing distance to about 20000 when the norm is about 8000. At normal distance you get a much faster FPS. At that speed its still fairly smooth. In any case, theres still plenty of optimisation to be done here so I'm pretty optimistic we can keep the FPS at a fairly high figure.
