Much of the fun of Seaquest is its simplicity. I like to play for a few minutes at a time in between other tasks just to keep my reflexes up. Also, the graphics in Seaquest are quite good, building well the underwater environment. Seaquest is hardly innovative, but it does fairly well even in its confined role. For example, in order to stop the ship, the player must turn the ship opposite te direction of motion and fire the engines just enough to slow to a stop without reversing direction.
Most variations involve two players trying to get the most kills.
Space War is somewhat unique, and for that I definitely have to give it a place here. The game's engine makes for very interesting gameplay. Unfortuantely, the graphics a very low resolution, but that is not enough to spoil a game which is this fun to play. This game is one of my favorite Atari 2600 games. The gameplay is lively and fun, as always, and the graphics are good.
