I feel like MineCraft are another model of a building type game. Its one that breaks down the simplest unit further than any previous game has, offering a modicum of control you didn't see before. The simplicity of it and ability to build complex structures hit on the same areas of the brain as Lego building sets tapping into something that was already there in many folk. There will always be a community for such things but this one is massive because you can do anything with it and people will always want to see how far that's taken.
W.O.W. is something that built on Blizzard's Massive success and desire for a continued revenue stream from faction based gaming. The lore they built up from Orcs and Humans in 94 to W3 was significant. They learned by studying NWN and Everquest and avoided their failings to make the biggest mmorpg but people still played NWN and EQ till their followups came out.
In the test of time category MMORPGs have the unfair advantage of being constantly tweaked and updated so it seems they're not quite standing the test of time so much as adapting to time to keep their appeal.
The table top games have the similar quality but its based more in becoming more refined or balanced in their Mechanics. (
The fact someone made this goddamn NPC enemy shows why table tops esp DnD is the greatest of all time ) (
Here's where the reference to that comes from...so hilarious )
IF you change form to suit your audience are you standing the test of time or are you changing and therefore admitting you can't stand the test of time as you were?
