Ironic this came up (again) because I was just looking at it yesterday.....there's actually only one machine that doesn't have multiple releases, over 1000 reviews at the top.....TZ (also the IPDB #1).....played it tonight, and it's easy to remember how well this machine stacks up to all the new shineys.
The top 100 is amusing to look at, but in no way reflects actually ranking, longevity and staying power of the game. Just my take, but a game should at least have several hundred votes to even make the list.
(also played my Spidey tonight, and completely blows my mind how fun some of these "not so shiney" games stack up to the latest)
