I suspect it may be an attempt to position themselves as non-threateningly as possible, by introducing themselves as being a boardgame company rather than an RPG company. Whether that's true, and whether anyone believes it, time will tell.
Thanks, my knowledge of the boardgame market is limited, and somewhat out of date these days.
I am very heavily invested into boardgames at the moment, and there are some companies that have started recently that are making waves with incredibly innovative designs and well supported on Kickstarter. Awaken Realms (who make Tainted Grail, Nemesis, and Etherfields) are one that I definitely watch, and they do story-telling games with character progression VERY well.
Gloomhaven is the #1 game on Boardgamegeek, and its sequel, Frosthaven, raised over $12 million on Kickstarter. That features dungeon crawling, character advancement, a linked (branching campaign) of about 90 scenarios, and strong tactical gameplay.
And then there's Serious Poulp and their "Seventh Continent" and "Seventh Citadel" games, the latter raised almost $4 million on Kickstarter, which also come into the same ballpark as Critical Role Adventures.
(Also consider Clank Legacy: Acquisitions Incorporated, and the Pathfinder Adventure Card Game).
Do I think Critical Role Adventures could do well? Yes, I do. But the pricetag may be hefty based on their description.
The other products seem no more than curiosities.
