OK so here’s the deal. I recall once trying to delete my game environment (my RPG game) and replacing it with a new one, and to no one’s surprise, it broke the game and made it unplayable (and I still don’t understand why). Back then fortunately I didn’t save it by accident, but I don’t want this to happen again. So my question is:
If I were to re-design my game environment, what should I be on the lookout for before going reckless?
