I missed a few posts before posting this message, but I'd just like to point out that someone already published a very simple "script" to be put in a batch file that backs up your save for a selected game. Combine that with the -preexec switch and you can get an autosave at the end of each turn before turn resolution in case you really need to load.
Personally, I'd rather just play the game, and occasionally manually save when I feel like experimenting.
