Will 1999 ever happen again?

[Morningbreath]

With even WoW making the news for losing subs hand over fist, does anybody else think a tougher MMO could be on the horizon?

Even though "sandbox" has become the latest trend I wonder if we're not too far away from a more challenging PVE MMO. P99's population has been gradually ticking upward since I started playing in 2013...I don't know about other people but I keep coming back for the challenge and rewarding nature of the game.
