Agreed:
I use a "cascade" saving on most games.
I'll save my games in like "version numbers".
1
2
3
4
etc.
If it's minor, or litle change, it might be a 1.1 or the like.
If it's like after something major, I will use the next whole number.
If you get used to this, you will save yourself a lot of time, especially when playing Myth II. And it's a good habit to get into.
