I'm thinking all those responses basically came from coding masters - he's the only one that I've seen alter the post subject O.o ...
Anyway, I did understand what you said - and I replied with a solution. Change the name of the second game to the name of the first - in the exact location in which the first game was when the save was made (because I believe the filename & location is saved too) and then load it... It should use the variables and stuff from the old and put it in the new - you'd be given loads of junk variables though.
An easy way for Alex to do this would be a "carry-over" or whatever setting in a variable - so that when loading it up to a new game/sequel it dumps the old variables and keeps the one's with that setting...
It MAY also be possible with existing stuff - use the game to output stuff to a filename - just need to know how the save file is encrypted that's all
