Thanks, guys. I'll try to get another one out in less than five months.
The time limit idea is interesting. It seems to me that one of the disadvantages of chopping up the larger actions into scene-by-scene battles is that context gets lost. A time limit would help restore the missing context here: this scenario isn't a meeting engagement between two forces, but a desperate ride to reach Théoden and crew before they are overwhelmed by the hordes of Isengard.
Re: YouTube: web pages and videos both have strengths and weaknesses. I try to enjoy each for what they are.
Videos allow more personality, and there is sometimes enjoyable tension in awaiting an important die roll. Editing is important, though. There's little reason to watch a movement phase for any but the smallest scenarios.
But I like regular web pages, too. I see the main advantage being organization, where it's usually clear what turn you're looking at and progress toward victory. (A few video producers do this, too, and kudos to them for doing so. But it seems unusual.) Also it's easier to skim a web page if you're in a hurry.
