Generally. Most free to play games seem to have conflicting anticheats. And hunt showdown (not ftp) is a big one. Some how every game my group decides to play has a invasive anticheat. Tom Clancy's Ghost division 2 doesn't work, I don't play that anymore but it didn't work when I tried anyway. Right now they are into warlander. The anti cheat in that seems to be hugely invasive.

A lot of competitive shooters have the craziest anti cheat stuff.
