That's not entirely accurate. The full phrasing used is "it doesn't have to be old to be classic."

Every square is a rectangle, but every rectangle is not a square.

Anyway, the important thing here really is the context of the OP's post. I'd have to go with Kid Ice on the timeframe cited, as that really is the classic time period for arcade gaming, and it addresses the OP's context. Exploration and creativity were at a fully saturated high point - a point that can never be equalled because 99% of video gaming ground has been covered by now. There may occasionally be new games that tread on fresh ground, but they'll be few and far between, instead of two dozen games or more per month.

And finally, I'll second Mad Planets and add Krull to the list.
