Why would I want to purchase the game again? can't I just put in the existing SN and download it? or can I?
Your very uneducated guess was right on the money! it is my DVD burner! I put it on another PC with a GF 3 card in it on a 2.4ghz pc and a standard SCSI Burner and it worked just fine. So I gutted the other puter for the SCSI burner... but had to upgrade the controller to work on the PCX slot. I only got 1 32bit PCI (standard slot) and my Hard card Server adpater is in it!. I have 3 64 bit PCX slots left. The mobo is basically all 64bit except the one pci slot which is dual 64/32. So I upgraded the old u2w controller to and Ultra320, which is backward compatable 64/32bit and was able to get my UltraWide to be seen.
A game as simple as this one as of design wise is a great stepping stone to more of an interactive type of play - maybe don't make it turned based, but a more free flowing game like Homeworld 2. Then you can participate in the battles. RTS games (if not already - there are only a handful of Turned based games compared to the rest of the RTS games out there) will be obsolete soon because they have some steep competition out there as it is with Turned based types. It is a good stepping stone for now. I'm very interested in playing it.
