The philosophy behind the current system is, however, that you can play the turn and have ALL data just by grabbing the result file. Makes it easy to do a turn on any computer with internet connection if you are not at home. Or to rebuild from scratch if you lost your hard drive / computer / whatever.
Changing that as you propose, Karibu, would mean you have to carry around your SE Data with you to the computer where you want to do your turn. And you'd have to keep making regular backups by yourself in case that something goes wrong, because you cannot recover all data from the .gam file.
