...dying meant that the game ends. No "game over", no credits playing, simply a black screen. You can't restart. Your IP address is banned from playing the game again and whenever you try to reinstall you just get a black screen. Same goes for when you buy another copy of the game. Let's assume there is no way around this.
Maybe you struggle and die in the first 30 minutes of playing due to a stupid mistake. Maybe you almost finish most of the storyline. Maybe you play for hundreds of hours and then die.
If such game existed, in whatever form (rpg/mmorpg/shooter/console, all doesn't matter, just pick what you find most fun to play).
How would you go about it? Would you just buy the game and play, let yourself be surprised? Would you read up on all tactics? Would you watch endless hours of streamers playing the game before playing it yourself?
