In truth, even this should be more of a 3D sphere than a simple 2D map.

• Shovel Knight is connected to the PlayStation 1st party multiverse by its God of War cameo.
• Tekken's guest characters connect it the Final Fantasy XV (and by extension all of Final Fantasy), SNK, and The Walking Dead.
• Speaking of Namco fighters, SoulCalibur is connected to Tekken by Heihachi and Jin being a guest in SoulCalibur 2 and 5, and by following other guest characters, we have links to The Legend of Zelda, Spawn, Star Wars, Xenosaga, Tales of Symphonia, God of War, Assassin's Creed, The Witcher, and Nier.
• Kingdom Hearts, of course, should be connected to the Disney region.
• There are a few connections to the Tommy Westphall Universe, a group of HUNDREDS of TV shows which theoretically all takes place in the mind of the eponymous autistic child. For example, CW's Arrow is connected to the DC multiverse. One episode of it had a reference to the Blue Sky meth manufactured in Breaking Bad. And Breaking Bad features the fictional "Morley" brand of cigarettes, which appears in The Twilight Zone, The X-Files, Buffy the Vampire Slayer, Malcolm in the Middle, etc.

No connection to Kevin Bacon
The map's invalid already
