Will it destroy WOW now that Asmogold and cronies are there?
The entire MMORPG genre is a dead, cooling star. By 2030, graphical MMORPGs will be in a state similar to that of text MUDs today—the most populous of which are lucky to have 100+ players online simultaneously. Also, the monetization schemes of MUDs make EA's shenanigans look like philanthropy, and the perks are most definitely pay-to-win.
WoW was never killed by one of its own kind, and never will be. It's the lich king of an undead legion.
I'm just glad I got in and played the right ones while the playing was good. I played FFXI starting from the NA launch for a year or so; I played some UO and RO private shards over the years; I played some pre-CU SWG; and most importantly, I played EVE Online from 2006-2012. This graph illustrates why that timing of playing EVE was ideal:
Basically, I was able to git gud during the great early years of the game, I got in on the ground floor of some cash grabs (wormhole exploration, etc.), and I was a well heeled veteran player just at the right time to spend years doing small-gang PvP on and off, taking hiatuses as I pleased, and generally enjoying the pinnacle of the MMORPG genre.
Even though my dragon hoard of ISK (around 400bn, after I gave some out to friends and a few Codexers) has no doubt been donkey punched by inflation, and it's been nine whole-ass years, I still have three heavily trained pilots and a lot of assets... though no doubt some ships I left parked somewhere unfortunate have been blown up/stolen.
But I'd never begin playing again, because it's clear that CCP have increased the emphasis on PvE and monetization of same through their cash shop, which they were experimenting with (to much booing) even years before I retired.
