In the future, when our souls can be uploaded into a simulation, the first generation has to be uploaded into an existing template as an entirely new, in-depth universe is not available. Pick a video game that you would like to be inserted into for eternity as a character. Obviously, open-world type games with a lot to see and do are preferable as super Mario or earlier gen games might get boring after a while.
I’d have to go with world of warcraft. Huge area with a lot to see and do. GTA 5 or maybe San Andreas is the runner-up.
