Definitely want to be in a large open world game like GTA or skyrim so you have room to explore for the rest of eternity. A mmorpg would be a grind like real life, so it would feel familiar, but at least you could have magic. I think the answer depends on if you’re a NPC or the main character in the game.
I still would probably pick Minecraft and spend eternity building working computers in the world, so I could play other games as well.
At least you would have space to explore and options to build. Being stuck in any video game for eternity is going to be hell.
