One of the best two player games of the golden age of the arcade was the game of Joust. Joust put the player (or players) against wave after wave of flying knights armed with lances. The players rode an flying ostrich or a flying emu. The computer players rode upon buzzards. The players could attempt to work cooperatively, but had to take care not to dismount the other player; which then may escalate into a discordant spiral of retribution between the players.
The game had relatively simple input controls. There was a joystick that allowed for left and right movement, and a button that would flap your mount's wings. It took great practice to be able to hover your mount effectively.
If you wren't fast enough in dispatching the computer enemies, the screen would be invaded by speedy and near invincible pterodactyls. There was the lava troll, that would attempt to reach up and snag you into the lava. You could attempt to break free, by feverishly pound the flap button. As well, after every few levels, a platform would disappear until you were left with a laissez-faire aerial melee. The enemies got faster and more adept as the levels went on. This game kept its players on their toes.
Some high scores from long ago and far away...
