Yeah, stats are basically summed up events. Problem is with storing that stuff, I'm still looking for a good data store solution (not a lot of free fully embeddable DB solutions for .NET to choose from it seems

and I don't want more custom binary serialization or ♥♥♥♥ like that

).As for dmustanger's reserved thing: Whatever is accessible in code can in theory be used. In the end for players that should probably be about everything the game knows about (e.g. what you can see in your UI menus while playing).
Added for the next release. instead of "location=DONE" it will be "SHOWINVENTORY DONE" though.
