Go Atari 2600,
Super Mario Bros. 3 was possibly the best game ever, But overall the Atari 2600 with games like Adventure, Atlantis, Haunted House, Pitfall, Turmoil, Worm War I, Yar's Revenge, etc. make it a more fun system.
Thank you, Mario, but our princess is in another castle! ... Just kidding.
the 2600 was good..i played that up until 5th grade (1991)
