SegaSince the very beginnings of video games, Nintendo has been at the very forefront of platformers. The original Super Mario Bros. for the Nintendo Entertainment System defined the genre, and became one of the most beloved games of all time. Following the success of Super Mario Bros., Nintendo released a number of games that rivaled their predecessor, and were able to hold their own as spectacular games. Games featuring Donkey Kong, Kirby and Samus Aran advanced their genre forward, and made the characters stars and icons in their own right. Although Nintendo was a driving force of the platformer genre, it absolutely has not had a monopoly on the market. There have been a number of spectacular games that have been created by other studios and released on platforms other than those belonging to Nintendo. Some of these games bring a lot to the table, and have offered creative and innovative advances to the platformer genre. If you're a fan of 2D platformer games, here are a few great games not made by Nintendo that are definitely worth a play-through.
