From my limited experience, I see the connections to multiple machines.
That could be a cool feature for Pinside to add to the Pinball Description Pages. Perhaps even it's own category titled Related/Similar Machines that link to the various related machines with a note to identify the relationship (i.e. multi-player version), etc...
And in that vein, perhaps even identifying the various Versions of a given Machine perhaps on the Detail Tab of the Pinball Description. Versions meaning (Standard, LE, Pro, Vault, 2nd LE, etc...), since the more modern machines seem to come in various versions.
Just a thought!
