It’s hard to beat Super Mario
Super Mario Maker is essentially two games - a design tool and a traditional 2D platformer.
The tool aspect lets you crib elements from several Mario games and toss them together into a level of your own making, which you can then upload online for everyone else to play. You choose the overall graphical skin from among Super Mario Bros., Super Mario Bros. 3, Super Mario World, or New Super Mario Bros. U.
This affects the way everything looks and sounds, and how some items are used and the background that you choose determines the stage and musical themes.
A real pleasure to play for any age of gamer.
Super Mario Maker is great
