Pinball is more fun with
friends, and as a result,
multiplayer games
are supported on nearly every machine built in the last few decades, and
some of the ones before that. However, I find that games with more than
two players tend to have
too much time between your turns to play, with
the result that you lose all the
continuity of a normal game, so
doubles pinball is probably the best.
This effect may have been
exaggerated by the fact that the only friends I ever played multiplayer
pinball games with on a regular basis were anywhere from moderately good to
extremely good players, so ball times were sometimes way out of the norm.
My writeup in the pinball and sex hypothesis has one story of a particularly
long multiplayer game.
