To all the bros giving advise in the sense of "get big youtube person to make video for mad $$$" I'm afraid that's mostly a modern myth/misconception actually.
Scientific research into the whole youtube video by popular person = instant piles of cash thingie shows that youtube personalities don't boost the sales of games significantly, unless it's a casual/funny or "youtube bait" game because people mainly watch the youtube stars for the person and not the game they are playing. If a more complex/2deep4u game wasn't interesting to the viewer before it has been shown by a youtube personality, it won't be after he's seen it either.
Also one has to keep in mind that most of the youtube audiences and followers of the bigger youtube names are across the board quite young and more fascinated by said casual/funny games.
Many popular youtube people won't even bother touching games akin to AoD because as noted earlier by someone else in this thread they don't
make good Television have shiny blinking lights and "achievement unlocked!" messages every 5 seconds.
Even your living god Total Biscuit himself agrees to this thesis in one of his later videos:

That being said there are some smaller niche channels from and for RPG gamers where people actually do watch to get informed about games of their niche and value the opinion of the youtube person because they have a similar taste to their audience.
So a campaign targeted at those kind of youtube channels with the goal of increasing visibility and raising awareness of the game's existence might work pretty well actually.
So in short if one were inclined to throw their resources at a Youtube campaign, in my humble opinion one should inform themselves in advance about whom to talk to and focus on those niche channels instead of just sending the game to the "top100 most popular youtube people" and simply hoping for the best.
Even shorter
tl;dr: some games do work quite well as youtube sales booster bait, AoD isn't one of them. The better approach would be niche channels focused on RPGs if one hopes for success with a Youtube campaign.
