WoW takes less than a week of play time to get to 80.
And that, for me, is the reason I only played WoW for about a month before deciding it was an infinitely forgettable waste of my time.
All MMO's are technically a waste of my time, but if I'm going to waste time I'd at least like to take something away from it.
The reason I think some people consider FF11 "boring" is because it actually required adventuring. Adventuring in and adventure game? How Novel.
In 11, to get a quest you had to talk to random NPC's not just the ones with a shiny thing over their head, which also means you get to talk to all the cool story NPC's that don't really affect the game but fill in some nifty history thereby enhancing the game. The fame and rank systems gave you a reason to quest other than just to grind XP. But because of this need to adventure and the fact that I had to actually be engaged with the world of the game is what made me love 11 and remember my time in Vana'diel. I can remember a lot of the quests I did in 11, I remember some of the NPC's by name, some of the cutscenes, and who could forget all those milestone long haul "unlock" moments. In 11 I might have only finished 1 or 2 long quests in a day, but at the end of that day I actually felt like i had accomplished something and was happy with my minuscule progress. And since almost every quest was a unique experience they were ALL fun(except for the frustratingly difficult ones, lol). And this is why every day in Vana'Diel was different and significant in some way as a gaming experience.
My time in WoW is almost completely forgotten, mostly due to it's ease of play. I don't remember any of the details, couldn't tell you the name of a single NPC, couldn't tell you the story content of a single quest. But I do remember how playing WoW went because every day was the same.
Run around without talking to anyone who didn't have a thing floating over their head.
Talk to all random NPC's with quest markers, accept quests without reading.
Kil 10 of something, kill 10 of something else, kill 20 of another thing, kill 10 of something else.
Return to town once all necessary items had been collected, 30 minutes later.
Talk to all NPC's with Quest markers without reading, get rewards.
Repeat until lvl 80, make new character.
Return to top.
After a few weeks of this I was done.
For some people gaming is about #'s, how much XP did I get? what's my DPS? how many levels did I get today? These are the questions asked by dedicated players of WoW and it's many lookalikes(There are also a few of these in 11, but their population seamed small).
For others Gaming is about story. Can I unlock PLD today? Wonder if I'm strong enough to make it to Norg yet? How are my LS mates doin today? These are the questions I think a lot of 11 players enjoy.
If there is one constant thing about every MMO is that XP happens. You'll get XP every day if you're playing the game. Not all the XP has to happen right now. You play the game in order to play the game. You'll hit 75, does it have to be tommorow? I played 11 for 5 years and never hit 75, because I was more entertained by the game itself and the players I played with that I was with the shiny numbers on my stat screen.
Give me a long slow grinding slog that's actually fun every day anytime.
