I did hope that you would recommend this game. I really really want to have it. Definitely a game I will look for in Essen this year. I loved the video game and the boardgame looks amazing.
To be honest Stone Calendar deals 52 damage after seven turns in video game, so basically a lot of times does nothing, but when hits it definitely helps. I got my copy of StS few days ago, but it's in Spanish 😢
I have to say, that is most likely a good thing; I found very hard to get games on spanish; its gonna be easy for you to sell it (and then get it on english)
Looks best at 2 players. I've seen some 4 player playthroughs that take 2-3 hours per act. At that pace you're looking at 6-9 hours for a 3 act run. Looks very fun though!
It's a very different genre, but I think you'd like this one too. You can check out Battle Card Game genre. Games like "Magic the Gathering", "Summoner Wars", "Mindbug" to name a few.
