I ALWAYS time travelled in the past games, one of my greatest memories come from wild world when i would travel all the way into the future or past with my little brother to see what would happen lol.
In acnl i did it all the time to speed up building and tearing down and getting fruit again, but after a while it burned me out. After that I promised myself i wouldn't time travel again but it never really got fun anymore...
Thats why I decided in NH i wouldn't time travel at all, so it'll hopefully wouldn't burn me out! And it worked yay! 1 year later, maybe skipped a couple of days or weeks, but I'm still playing and enjoying
I did do some timetravel tho, but only a few hours forward or back in the day, if i needed to shop after a long workday or when i needed photos in a different light of day. But besides that I kept my promise
I do really like time travelling and have no problem with other people doing it! I just know it ruins things for me personally so thats why I myself don't do it
i don't consider it cheating or anything
