I just got tomodachi life tonight and ADORE my Bonnie mii (dont get me wrong i love foxy too but the bonnie mii has made me a bigger fan of Bonnie) I have noticed miis will start to miss you if you are gone for too long (ive seen this on Miiverse) so will tting in ACNL affect Tomodachi Life?
I believe, if you time travel in animal crossing it won't affect your tomodachi life game and vise versa, unless you changed the clock time in your 3DS then that will affect all of your games. But you can time travel at your desire xD
Sort of. When you time travel TL sees it as cheating (even if it's just for Daylights Savings Time) and the shops won't reset for a few days. There might be some other side effects but I'm not sure.
But if you mean time traveling in ACNL, no, that will not affect TL or any other game. TL will only be affected if you change either TL's ingame clock or the 3Ds clock.
