I'd stay well clear of my future kid's savegames, out of self-persevation. Trust me, what goes around comes around.
"Wha..? What happened to my Minecraft? Where's my fortress..? Why am I locked inside an unbreakable glass casket on the ocean floor..? Where's my hunger bar?!
I... I can sometimes see the sun. That radiating block of light and hope... Flickering through the murky waters, down into my prison in the abyss... A mocking taste of freedom, out of reach. Why?
Each day, I see it flitter past, and regain a taste for freedom when I know I will be imprisoned down here. Forever."
Not to mention, I wouldn't want to end up in a situation where the kids go "Well... We could let you stay at home and pop in to visit and check up on you once in a while, but we still remember what you did to our Elsweyr saves back in the day. Guess who's going to Kinsford asylum, you senile old sod!"
