Dr. Mario is the game you're looking for. It comes with a 1-4 player co-op mode where people can just grab another remote and hop in and out without needing to change options or even pause. It gets hilarious when 4 people are trying to play at once, in the same jar with the same viruses, and 2 or 3 pills are simultaneously falling really fast. Other than that, the regular Dr. Mario mode is online with friends or strangers. Also, the game is still perfect.
