Mario & Luigi is a remarkably hands-on RPG, the antidote to JRPGs and their cold, unflinching stats. Numbers underpin the experience, but the game is built primarily on what you do with your fingers. Hammer attacks are amplified if you tap at the apex of the swing. A single jump becomes two if you press as foot touches head. Even incoming attacks can be dodged or countered, as long as your timings are sound. It's a system of forced engagement and very engaging it is, too.
