No it's not, Jackbox is a great party game, Buzz is a great party game, Singstar is a great party game, Just Dance is a great party game, Mario Party (most of them) are great party games, Wii Sports is a great party game, even Wii Play is ok.
1-2-Switch is barely a game. It was created for one reason "what can we do with these new controllers." Fun took a backseat, as did anything remotely related to rewarding skill.
I digress, everybody I've played it with has had a blast. Sometimes games allow you to make your own fun. Get the right crowd and 1,2 Switch is very effective.
