Although you may have thought this was the VideoBrain
equivalent of Activision's Tennis, it's really just a fancy
version of Pong, with tennis players instead of paddles. Tennis
does offer what is referred to as "Rushing Variations" where
the paddle slowly moves left and right in addition to up and
down, but the player doesn't control the left and right
movement (the player moves on his own). The movement
seems very choppy in this game, which is an unforgivable sin
in a Pong game (after all, up and down movement is all there
really is!).
Tennis does have a few nice things going for it though.
There is a row of spectators at the top of the screen,
and a little man comes out to drop the ball in front of the
player between each serve. Tennis also features 95 game
variations and supports up to four players (assuming you can
actually find four controllers). However in the end
Tennis is really just a Pong clone, and a weak one at that.
