The CWAL Rubber Room
"Why is it that every time a bunch of CWALers get together, they always end up saying 'That poor waitress....'?" - Dark Nexus
Also, this reminds me of the excellent novel "REAMDE" by Neal Stephenson, which was basically a book version of a Hollywood techno-thriller movie but with actual believable technology. It wasn't set entirely or primarily within a video game, though, so I don't think it would qualify as "LitRPG"
