I don't really think so. BIS was pretty fun, but it didn't have enough of the gameplay style I loved in the first two games. I never finished BIS, and I've never played DT. I'd like to finish BIS someday, though, as well as try out DT.
Well, I mean this drawing is already super masterpieceinized, so I wouldn't mind. Plus, I think all games from the Mario & Luigi series are off the hook.
