I've always played the game solo. For the past year or so I've been playing 2-handed (via OCTGN). I think the Dol Guldur quest inspired/forced me to make that switch.
Overall, I think 2-handed playing has made quests a little easier for me, I think it also makes them take longer. Twice as long? I don't know. I certainly have to keep more stuff in my head at any given moment, which might slow me down in my decision making. But the bottom line is that I feel like I need at least 2 hours to finish a quest, instead of 1. (yep, I'm that slow!)
I would like to play more often. One possible way to do that would be to switch back to 1-handed play. However, I am worried that if I do that, I will "miss out" on some of the game mechanics which only work when two "players" are present. Also, I am worried that I will run up against a scenario that is really hard to do solo, like Dol Guldur, and get frustrated at my inability to pass it.
For example, right now I'm making my way through the Dwarrowdelf cycle. I'm playing 2-handed, with tons of dwarven heroes and allies. Dain is a godsend. I feel like if I were only playing 1 hand, Dain would be less cool, since he needs to stay ready, and I would only have 2 heroes who can actually quest and fight (effectively), unless I find ways to ready Dain. I might therefore never have been tempted to try playing with Dain, and would miss out on the whole dwarven army gameplay. And that would be a bad thing, since I am enjoying it so far.
I know, I've read that some people think dwarves are "boring", but remember, I'm a couple years behind you guys! I haven't yet "opened" enough cards to try other army types. (I've bought all the cards available so far, and can of course use any cards I like via OCTGN, but I prefer to only use the cards available at the time a quest was released).
So my questions are these:
1) Are there other mechanics coming up which require 2-handed play to be effective (or even feasible); will I "miss out" on a significant amount of cool game play if I switch back to 1-handed play?
2) Are there quests coming up which are extremely hard to win solo (like Gol Duldur was)?
3) For those of you who have played both 2-handed and 1-handed, do you find 1-handed play significantly faster? Easier? More fun?
4) In order to play all 4 spheres, do you play each scenario multiple times, once with 2 spheres and then again with the other 2 spheres? I used to do that, in order to experience all 4 spheres. However, note that it increases the amount of time it takes to "finish" a scenario (since you have to do it twice).
5) What other things have you noticed about 2-handed vs 1-handed play, and how often do you play each way now?
Thanks!
