Feel free to create a one-off or regular event for either/both of those.
The CoD night is on Monday evenings.
Technically it isn’t an Xbox-only event, just no-one hosts a PS4 room.
You could mention to @beers_and_leafs about co-hosting that existing event with him if you like.
I’d join in on the BF nights when I’m around and I think @SoInZane has all the CoD titles (I only have the older ones).
