Um yeah...
The "Dreamcast 2" supporters.
wew.
When I first started poking around old console forums I stumbled on Dreamcast Talk. It's a decent forum group, they showed me how to get my Dreamcast back online to play weekly games of Quake 3 and Phantasy Star online. A lot of those forums were dedicated to troubleshooting online connections, how to get the most out of a VGA box, hidden gems in the game catalog...
It was a good mix of hardcore fans of Capcom fighting games, Shmup enthusiasts, and people who wanted to get the DC back online.
...and then there were a couple of people who got off on the idea that Sega had a secret new console in development.
It seemed every week they would post new "evidence" to support this, and every time they would be BTFO by rational people.
I honestly couldn't tell you if they were trolling or if they really were that batshit insane.
