What is the best way to save a game?

Dear CS Developers and Gamers:
     I need to save data to a file for a game I'm helping with. I have seen the csSaver class that it saves objects to file. Are object descriptions all that is required for restoring a game? I see the celPersistence class aswell which will be helpful for CEL side of the game. I would like all experience anyone has to offer on this subject.

csSaver is for storing meshes, level data etc. This is probably not what you want - after all, the models and levels are the same for any game, saved or not. You more likely want to just store the entity states.

"Are object descriptions all that is required for restoring a game?"

Depends from your game. When you use CEL, you can save all CEL entity easily.
