In a little more than an hour with Mario & Luigi: Brothership, I got to play through the main missions on two particular early-game islands, Twistee and Merrygo. While it definitely felt like these were building the groundwork for bigger challenges and more intricate gameplay to come, the slice of island-hopping upon the brothers' mammoth seafaring vessel, the ship-slash-island Shipshape Island, that I did experience hinted at the larger potential of what's to come.
