Two hours of raw gameplay playing Adventure Mode in a Crusader class level 35-42. Adventure Mode for me is very fluid and enjoyable. I feel the campaign mode is long and less fluid. Campaign mode can be monotonous long before the 1000th time going through it.
Adventure Mode on the other hand is completing a random Bounty at a time. You choose which Bounty to tackle, and which area of Sanctuary or High Heavens you want that Bounty to be at.
Some are short, others even shorter. It feels like the perfect gameplay experience for someone who doesn't have 2 hours to play, but 20 minutes or 40 minutes. You complete as many bounties as you wish in the time-frame you wish, and you know you will be done before the time you need to go take a shower to go to college or to your job, or to the movies with a friend.
Best yet is the rewards. Every bounty you gain a Horadric Cache, monsters might drop them too. The bigger ones are sold by the Horadrim for 100 Blood Shards. Some have a chance to drop a Legendary item. The way this new mode is designed will likely make players level 70 go this route to gear up. It's so fun to open the Horadric Cache and see this bunch of loot come out. Even if your leet Legendary didn't drop, lots of Blacksmith materials pop for you to craft stuff.

Note: On Tuesday or earlier, I'll take video of the Crusader at level 70. I am level 61 right now. Working hard on it. I'm also going to gather all the Crusader skills in a list and add short videos of each skill+rune variant. Stay tuned.
