I have one group I play in where there are 7-10 Players. It's pure chaos, though since we play very infrequently and a lot of the players don't take the game too seriously it somehow works out.
Still would not recommend unless you like roleplaying with your fellow players until you get to your turn of GM attention.
This reminds me of the stupid Gigabyte RGB software...
Not sure if this is till the case, but for a long time the kernel driver had a known unpatched security vulnerability. And uninstalling the software did not remove the kernel files, so now your system is vulnerable until you reinstall Windows...
And I fully expect some kernel level Anti-Cheat to be no better in this regard.
