I really disliked the drawn-out/tedious nature of Dream Team where the game mostly felt like one big detour, so i have a feeling I was right in passing this one up, quests are cool and whatnot I just kind of like my content too feel fun and meaningful and I can't stand when games drag on, if there are like fetchquests or such that are mandatory that sounds especially bad, I like the Mario & Luigi humor and combat system but they put out so many of the games anyway (and I haven't even beaten Superstar Saga) so I guess I just don't feel the urge to play it, and based on what you said it doesn't sound like I should feel too bad about that XP
You were right to skip it. If you aren't as patient than I am then this is not the game for you. A friend of mine on a Discord server was absolutely pissed about the game and how Luigi was treated by Starlow.
