I usually don't post my opinions on games until after I complete them, but I made an exception since this one is long (it's said to be around 4 to 6 hours, hence it's price of $10 dollars per episode as opposed to the now standard $5). I played through the intro and the first trial for Graham's knighthood, and I loved it so much so far I had to share my thoughts. I was wondering if they would go the route of modern Telltale games, as that seems to be a market that Activision would want to tap into. The result is a little bit Telltale, a little bit classic Sierra, and a whole lot of fun (the humor in this was said to be inspired by The Princess Bride, and there's definitely a lot of that, as well as other irreverent comedy such as Monty Python).
So far, it actually takes the Telltale formula to the perfect level in my opinion, mixing in the right amount of QTEs and action sequences with classic adventure game puzzles and choices and consequences (although we'll have to see how the consequences play out in later episodes to see if it reaches the levels of games like Dreamfall Chapters). There's the choices and consequences (old King Graham, voiced perfectly by Christopher Lloyd, mentions that his younger self had a choice between several options, each of which would have consequences). There are QTE's, and there are ones where you have to push the button repeatedly, but they make sense here as they're presented as things such as chopping a tree or rowing a raft, rather than just arbitrary things like summing up strength, and the amount of button pressing repetition is never excessive. They also have first person shooting sections (with a bow and arrow) that are handled really well (and sometimes even happen in the heat of the action, which adds to the tension in my opinion). But, there is also an inventory and puzzles, and not ones where the solution is right next to the object, either. The areas to explore are rather large, and the solution might be location far away from the problem, which bridges classic Sierra with the modern adventure game formula together excellently.
The story is exactly what I was hoping, as it's clearly both a sequel (as well as a prequel in parts) and a re-imagining. The set up of old King Graham telling his granddaughter stories of his life works well for the game, as it gets to tell new stories never told before, and for the stories that it does revisit (such as Graham's quest to get the magic mirror from the dragon), any changes to the story can be chalked up to Graham embellishing a bit to keep his granddaughter excited.
