Super Mario Bros Deluxe

Super Mario Bros. Deluxe on the GBC is an impressive port of the 1985 game with much-needed quality-of-life additions like a save feature and world map. It's stuffed with extra content, including the challenging, previously Japan-exclusive Super Mario Bros.: The Lost Levels, a competitive "You vs. Boo" speed-run mode, and a Challenge Mode that adds replayability by tasking players with finding hidden red coins and Yoshi eggs in every single level.

Real thoughts from real people:

"It's almost the definitive version of the most significant video game of all time. Screen crunch is the downside, but the sheer amount of content makes up for it." — User LifeIsOnTheWire

"The Challenge Mode is brilliant. Hunting for the Yoshi Eggs made me explore parts of the levels I had ignored for 10 years." — User GameBoyEssentials

"Unlockable Lost Levels blew my mind as a kid. I couldn't believe they hid a whole second game inside it." — User dasLast1
