The Nintendo DS was a weird point in gaming history where dev studios were trying to work out how or if you should use 2 screens for a game so you get some incredible games like The World Ends with You tied to some insane combat system that nobody would ever design today
@BrodieOnLinux I had one and it was a ton of fun. I really liked it. Some of the games I enjoyed on it include Sonic Colors and Spider-Man: Shattered Dimensions.
