Or I could simply use more even sheets... But I have read that too much isnt healthy for C2 stability. Guess I will find out
Where have you heard this?
I have always used multiple Event Sheets and attach them to a Layout when needed.
Just a basic setup would include maybe 10-15 Event Sheets, all utilizing one aspect of the game mechanic, such as Collision, Movement, Generation, etc.
Never come across an issue yet.
