SMU undefined is part of the MAU. There are several connections, including references and musical cues, that tie it to and. It's not a perfect continuity, but none of it is. I tried to explain it in the MAU article.

Video games are tricky. Some video games are part of the series, like there's one for and two for. But just because they use the voice actors doesn't mean they're part of the series. Take the upcoming Spider-Man: Shattered Dimensions for example. It uses voice actors from four of the last five Spider-Man series but is not involved in any one.
