What game is it and how are you doing?
BONUS QUESTION: He instead offers you $1 billion if you go to the Mortal Kombat universe, join the tournament and survive. He’ll have Raiden train you for a year, then the blood splatters. Do you accept?
BONUS BONUS QUESTION: He offers to send you to a video game world of your choosing, only you can never come back home or contact anyone here ever again, not even with in-universe abilities. Do you accept and, if so, which one?
Same as @HelixDab, System Shock would be bad, but as a regular person living in the world I could make it for $20 million. Citadel Station? Not a chance, not for all the money in the world.
Bonus Question: Fighting in a Mortal Kombat tournament? No. After a year of training I’m still going to die in the first round. No amount of money is enough.
Bonus Bonus Question: This previous questions were easy. This one’s hard. I’m sure I could find a video-game world that would be pleasant to live in, potentially much better than our world, but I’d have to trade all of my family and friends for it. I’d strongly consider it if I found a world where I could be effectively immortal and have a good life as well—making it a very narrow set of options—but ultimately I’m not sure what my answer would be.
