I think so, it's pretty easy to pick up. I play against my kids who aren't big action gamers (although they do love some arena brawlers), and I don't feel like I have to go easy on them for everyone to have a great time.
It does have a pretty high skill ceiling, so it could get that way, but it's worth a shot in my opinion; it's a ton of fun.
Depends, it can be quite easy to kill yourself in Duck Game, but you can also get lucky sometimes too. Have you tried to just go easy on them 😂, if that doesn't work, maybe Mario party might be the better choice in that situation.
