Back then, in 2014, I couldn't think of any instances off the top of my head, but now I have a couple.
- Dying Light should be played strictly single-player, not 2P, let alone 3P or 4P. I posted the explanation on Discord at some point. I'll find it later and copy-paste here.
- Hunt: Showdown should be played 2P, not 3P. Again, I've explained why on Discord and will copy-paste here later. I will also update my review with the explanation since, when I wrote it, 3P wasn't in the game.
I'll post more examples when I run across them. This is a very valuable thread for people who like MP and co-op games (i.e. anyone with a brain) so I am stickying it in the Online forum.
