Wish1, A dungeon that exists in its own dimension, but which can open and close gates to any existing world as I see fit, and which comes with a system based on the Holodeck from Star Trek, where I could not merely buy pre-designed stuff from some boring list with some dungeon points but rather a one, where I could produce anything I want, environments, items, creatures, etc, by simply giving verbal commands to the system, which would then do the hard work... and all free of charge and without limits of course.
Wish2, A video game character creator like ability with which I could not only design and redesign my own race, body, age, abilities, etc, at any time, as many times I want and any way I see fit, but one which also allows me to change similar changes to anyone else I want.
Wish3, A video game "save/load" like safety net system, where I could produce any number of save points, to which I could return at any time to redo whatever I want, armed with the foreknowledge of what happened the last time. A system which also automatically returns me to the last save point
if I get killed.
