There are a lot of arcade games realized with MMA, including: 2048 (2D and 3D), Sokoban, point 24, Gomoku, Snake, Minesweeper and Tetris. As well as video games like minecraft and SimCity 3000.
However, one classic scrolling shooter arcade game named "Raiden" (means "thunder and lighting") is missing. Here is a prototype of that:
