I think you have to keep in mind the fact that the "Top 100" list rates Deadpool above Twilight Zone. In other words, it's heavily biased towards newer games.
Even with that bias, MM still is at the top even though it was designed in 1997.
I'd like to see the same list of games rated 20 years from now. We've had 24 years to play MM and 28 years to play TZ and many of us are still not tired of them yet. Will the new games endure in the same way, both playwise and mechanically/electronically? Only time will tell!
