As I see most of you doesn't give a damn about startcreatureculling and starttileculling,
That is There should be some standard way of showing all options of the game and showing it to the user , so he is no longer confused about game internals.
How about storing the settings in XML file ? Would you like to have one big file GameOptions.xml :
<Option1> Enable </Option1>
<Option2> Enable </Option2>
<Option3> Enable </Option3>
<Option4> Enable </Option4>
I could come up with some xsd template, but first say your word ...
