This may seem a bit silly, but there are many games on Unix SYSTEMS that can help you learn to use VI. These help particularly with the basics. Although I don't know of any games that help with every vi command, I do know of a few that will help you learn to use hjkl to move the CURSOR around. NetHack, a rouge-like game, is particularly good for this, as it is a large game and can be entertaining for quite some time. Not to MAKE the other games sound worse, but some other ones are: rouge, moria, omega, worm, and SNAKE.
