TOP 5

1. The Hills of Emyn Muil : I like easy quests, I like not to be overrun within the first 2 rounds. Emyn Muil was the adventure, which I played very often in the first months to learn the game and to get more experienced. Maybe cause of that it gets a nostalgic bonus. Wonderful and interesting locations, I liked to explore them with my heros. The only drawback: in solo sometimes difficult to draw enaugh locations (grrr... The Steward's Fear, I mean you too!). Nowadays we finish that scenario in max. 3 rounds, what is a big shame, I'd like to play 10 rounds. :-)
2. Encounter in Amon-Dîn : As I said before, I like easy quests and Amon-Dîn is very easy. The game-mechanic is innovative and a lot of fun. My heros are always looking forward to rescue villagers. Apart from this I am impressed by the wonderful art, FFG seems now to hire one single artist for 40% of the cards of a certain scenario, which makes it unique and recognizable. Last point: Lord Alcaron = greatest objective-ally.
3. Escape from Dol-Guldur : Surprisingly I added the last of the Coreset-quests in my top-5-list, of course not relating to solo-game; I never played it solo and I never want to. But in a Multiplayer-environment it's still challenging and a lot of fun. Since I hate spiders, its great to kill them there :-)
4. The Siege for Cair-Andros : Vice versa! This is a new entry in my list and pushes old Nr. 5 (=Redhorngate) out of the list. Before I hated the quest due to difficulty and insane effects. Now that I have constructed a heavy-siege-mono-tactics-deck, the scenario got beatable, of course not all the time, but I got a nice average. Unfortunately in MP less fun, unlike you construct with your mates together your decks, ideally only tactics.
5. Foundations of Stone: So many has already been said about it and I cannot really add anything new. Only this: Burn in hell, Sudden Pitfall!!!

Of course there are many other cool quests. High points I usually give Redhorngate, Rhosgobel, Seventh Level and Into the Pit. The Steward's Fear has big potencial.

1. Foundations of Stone: . There is just nothing bad about this quest apart from not being conducive to solo play.

I'm not sure if that was just a poor choice of words on your part, but there's no way this quest is "not conducive to solo play". Just because you miss the extra twist you get from it in multiplayer doesn't mean it's not a highly enjoyable and replayable solo quest in its own right - still more so than most others and therefore easily in my top 5, based on solo play alone.

Well it is also in my top 5, so I think we agree here All I am saying is that unlike many quests that have no functional differences some are designed for and work better in a multiplayer format. This has zero relation to it still being fun solo, it is. I play it solo all the time, BUT that doesn't change the fact that when you consider reasons why something should be in a top 5, having the base design favor one type of play mode is a drag factor that deserves comment. It obviously didn't worry me to much as it is in my top 5... but as I said.. this facet of the quest had to be mentioned.
