splatoon... oh wait humans are extint there
mmmmh fire emblem...no..too much war
mario....no kingdom that is attacked lots of time mostly by a giant turtle and its army isnt safe
pokemon.... oh wait, some pokemon are very dangerous accounding to the pokedex
maybe housamo, it has my lovely husbandos and even if there are people with dangerous powers, they can only use them in a game,only the players who are playing at that time can be damaged by those powers and when battles end, everyone revives and..... OH NO,RIGTH NOW THE ENTIRE WORLD HAS BECOME A BATTLEFIELD FOR THE GAME, WITHOUT THE LIMITS OF HAVING TO PLAY THE GAME,THERE GIANTS MONSTERS IN THE SKY AND EVERYONE IS DESESPERATE FOR SURVIVAL
i guess that for my safety i would choose the "persona world" for most people its like our own world, and igor and the persona users protecs everione always from the evil gods or wathever that happens to wish to destroy humanity
