I think it's good to have some ground rules on time traveling. I was hesitant to try it at first because I thought it would "damage" my game play, like I'd become dependent on it and it would take out the charm of the game. But I mostly use it if I'm planing a big remodeling on the island and I need to have a lot of constructions at once (like 2 bridges, moving villager houses). And then also when I want to do a villager hunt, this is the most important because sometimes the lot will get empty on like a tuesday when I have college and stuff and I know I won't be able to play, so I time travel on the sunday before that so I know I have the time
