Pinball Gold Pack, but considering the sheer amount of content, it's hard to argue with the math. The Pinball Gold Pack crams in five games -- Pinball Dreams, Pinball Dreams 2, Pinball Fantasies, Pinball Mania, and Pinball Illusions -- adding up to a total of twenty tables for only ten bucks.
If that's not enticing enough, you could always grab them for the historical perspective. Specifically, the games were developed by Digital Illusions (A.K.A. DICE) -- the studio behind the Battlefield series and Mirror's Edge -- all the way back in the grungy, flannel-covered decade known as the 1990s. Crank up the Nirvana while playing and you'll pretty much get the whole experience.
