Some games have different options to change weather or not you respawn and some games such as skyrim have exploits that give you infinite health so you never have to respawn.
I love to discover exploits in video games! I think it goes back to when I had a Commodore 64. I had a cartridge that would let me edit any running program. So, I was able to edit the high scores or change the difficulty of a game...etc. So much fun!
