Finally got though a game(OK, I won and was rewarded as being the equal of Louis XVI, but that's another matter!). A few hints, as I finally did get the game to stop acting really wierd.
First, disable the AA. After I did that, I stopped getting wierd graphics (GeForce6600). Its so easy, even a philosophy major like me can do it. Make sure you have the right setting to disbable AA in the game options too.
Next-- really, really important and really, really obvious, but WATCH OUT FOR ACCIDENTALLY CLICKING WHEN THE GAME IS TRYING TO SAVE!!. That just about the oldest crash causer I can remember, but when response time is sooooooooooooo slooooooooow like it is in this game, its easy to do, and, when the game files get over 400 MB or so, it'll get you every time.
Also, watch out for moving across the map quickly-- that a sure way to get one of thopse lost audio stream comments that come right before crashes.
I'll bet a nickle there is a memory bleed somewhere, and my guess it it will be faily easy to correct one its located. But, in the meantime, before making a lot of exotic modifications in your computer files and drivers, try the easy stuff.
All that being said, the game still crashed about every 5-6 turns after the year 1990 or so, but most of the time I could see how it was my fault (see above). Cool, Cool game though. Wonder how great it will be when it reallyt works?!
