"Pro Wrestling (プロレス Puroresu) is a Nintendo Entertainment System game, as well as a Family Computer Disk System game for one or two players first released in 1986. The game was the first wrestling game on the Nintendo Entertainment System and was ranked 172 on Nintendo Power's Top 200 Nintendo Games Ever.
The player chooses a wrestler with unique skills and presses various combinations of buttons to use different wrestling moves. It is possible to leave the ring; however, a player who does so must re-enter the ring before the referee's 20-count. Failure to do so results in a loss (via count-out) or a draw (double count-out), if both wrestlers fail to re-enter in time. (Note: The referee's count is broken only after both wrestlers have re-entered the ring. That is, as long as at least one wrestler is outside the ring, the referee's count continues. Moreover, it is possible for a wrestler to be counted out while executing a Plunger if he has crossed the ring ropes by the count of 20.)
The game was one of the first wrestling games to feature an in-ring referee. The referee in the game is fairly accurate. For example, whenever a pinfall is attempted, the referee must run to where the two wrestlers are, lay on his stomach, and begin the three count. In effect, if the referee is on the other side of the ring when an opponent initiates a pin, the player will have additional time to try and escape. The game was also the first wrestling title to feature a cameraman at ringside (though he does not interact with the wrestlers)."
