I don't see the "entirety" when I'm playing the game. When it comes down to it I'm back in yet another undead-filled end game zone, having to face yet another undead antagonist, spamming #1 on the millionth undead I've fought between WoW, Rift, and GW2. It's old.
Maybe if I had played GW1 first it would have made a difference, I don't know. Regardless, it doesn't change the fact that I like to see and experience different things in different games, especially new games where everything should be, "Shiny!" I'm not an MMO connoisseur by any means, but of the 4 I've played in the past 5 years the only one that was a vast departure from anything else I'd seen was Tera and as far as I know it's still considered to be "fantasy".
