Trapped in a VR game

[Jumpercable2]

I want to do an RP where our characters are trapped in a VR game like Sword Art Online (based on a fandom we both like), and we have to team up to survive.

I wish I knew more about .hack cause I would suggest that, but I know a little bit about SAO. They die if they try to disconnect right? At least at the beginning?

In SAO, they are unable to disconnect at all.  It uses "Full dive" VR, which is essentially like being asleep while the game is pumped directly into your brain.  You can only voluntarily leave the game by logging out from the in-game menu, (the main character was a beta tester for it and confirms that the option did exist during that period) but after the game went live the option to log out disappeared.  But you are partially right in that the game will kill the player if someone else in the real world tries to disconnect them.

I've heard of .hack, but I've never watched it. Is it the same premise as SAO?
