Mario 1: Started it all! A fantastic game with a lot of mystery (warp pipes, -World). It's just classic!
Mario 2: Very dreamy (no pun intended). A large selection of characters, each with different strengths (unlike Mario 1). A strong attempt at keeping the genre from getting stale!
Mario 3: Return to the classic style! Lots of powerups and suits (rather than various characters) to allow for different strengths and game strategy! Cool warps. Into of the 'Map worlds' into the Mario Series!
