While calling each of these modes a "VIDEO GAME" was a liberal use of the term, the addition of so many variants on a simple concept like Combat made the game. I can sit and fiddle around with those stupid little tanks for hours because the sheer number of options is enough to provide ongoing stimulation to my A.D.D.-riddled mind.
The "28 VIDEO GAMES" in Snakes on a Cartesian Plane take that same mentality and apply it to Snake. And unlike Combat, you don't need an Atari 2600 or a second player to enjoy it. Not all 28 games are winners, but there are so many of them that it hardly matters. (Check the Options menu to unlock everything.)
There are plenty of Snake knock-offs, but this is easily the second best I've seen. (The first, of course, is the four-player Anaconda mini-game with the amazing music from TimeSplitters 2.)
