You might be surprised to see this title on this list, but the Lost Vikings crew (made up of Erik the Swift, Baelog the Fierce, and Olaf the Stout—sorry, no Cyhi da Prince) provided some surprisingly challenging puzzles to go along with their trademark humor. But the best part was that, unlike most Sega games, the game actually came with passwords; they were given out after you completed each level, so that you could return to said level even after you'd turned the game off instead of trying to beat it in one sitting like most Genesis games. Which makes us wonder: WTF did we ever do without memory cards?
