I'm in the trying phase of the game, can't write a full review now, it would be like writing a book review after having read a third of it
> How WAS the game?
Fun, the gf loved it. I think it will interest many newbies to try a regular D&D game.
Me, I think it's fun, but I still prefer the regular game by a mile or three

But it's a fun board game.
RLish? Not really, even if they made an effort on the atmospherics with the card descriptions. We are more stressed than spooky. And a table game can't be spooky. And its theme is close to EtCR, without the demons and the ooze everywhere. Monsters are gothic.
Tough? Yes, it is. There are two random aspects that can decimate the party: the d20 of course, and the encounter cards. In the game, you have to take an encounter card if you do not explore (add a tile), and many of these are traps (if they hit: 2, but still 1 hp damage if they miss). Considering the party has 6-10 hp each, it's deadly in the end. Yesterday, we were close to finish adventure 3 and kill the Villain, but a trap killed three person in the party of four. TPK.
There is something deadly with the encounter cards as in th ebook, it can be softened for an easier game (option 1 as David do, you get a monster with a white triangle tile or an ancounter card with a black triangle; option 2 when the villain appears, you stop drawing encounter cards when you do not add a tile).
Oh, and yes, one PC has to be the cleric.
The wizard is quite weak, and gets killed often, event if he stays behind, because of the traps.
> How long it takes after you learn the rules?
About an hour to read, and the first game took about two hours. The games afterward took about 1h-1h30.
> How many scenarios are there?
13, but I guess people online will add new scenarios to those proposed.
> Is there replay value?
Yes, it's everytime different.
