I like the troublesome adventures, the one you put the image of...but the model for the Iru mage guy seems a bit off.

What the fuck!  How come this never spawns for me!  Conspiracy!  

I really like one I have only seen once, where you have to defend a group of priests from an unruly mob - or join the unruly mob.

Also the Arena & Assassin's Blade quests, especially the latter when you come to the final victim...

yeah, its not the quest, its the prize

The arena of course.

Please stop teasing Lord Xia, he's twitching so bad his eye patch keeps switching sides!

Right, again, Joasoze -- Good Observation !

For my part, I am not really all that RPG/Quest-oriented.  I prefer to play E:FE as a kind of perverse 4X game, where the first two X'es (eXplore and eXpand) are partially/purposely crippled and twisted.        

For that reason, I usually prefer the shorter, simpler quests, where I can snag some (non-purchaseable) useful and interesting prize, especially in the early part of the game.  I  do  have a favorite prize so far.  I really liked obtaining "Kitty" in a recent quest.  As a Mage's "familiar", she is way cooler than some old wolf or dog.  For an early game companion, she is pretty darn powerful too; and considerably preferable to some lumpy Ophidian reptile ...       

To actually answer the question, no I don't have a favorite quest.

I would like the quests to be both more epic in scale ('completing' a quest component a certain way will open up different quests later on, etc) and I would also like to see their completion effect your game quite a bit more. 

Right now I see quests as a mild diversion so I can get a crap load of xp and lootz.

Maybe get your author buddy to design some quests?

I like the quest, i like reading them and I enjoy doing them.  It's good fun.  I don't expect every quest I get to be some major Destroy the One ring quest.  But overall I enjoy them.

Hmm....a quest that spawns another quest.   Sounds like a feature for the quest wizard. I'll look into it.

My favorite is the various random events.  Meteor Strike is a good one.  I also like the Spider & 3 brothers as that gives you different options for completing (and I love the brothers as units).

I really dislike quests and caves that are betrayingly powerful, its ok to have a "You got eaten and beaten" once in a while, but right now I see lots of them.
I like that somequests have NO combat, thats really nice, gives a break from the never ending "beat this" "Whack That" playstyle atm. So more quests in the style of escort and... whatever riddles etc.

On a more serious note, I think my favourite quest is the assassin's dagger because it has several steps to it. Too many one off quests. It would be neat to start a weak quest that extends for many steps ending in a major event that you have to really work hard for. Not for some game breaking item, but for something that you can't get from research.

I agree with kongdej, in that the game needs more puzzle quests
