I played it a couple times! It’s by the people who did Undaunted and from what I hear is very similar so that’s probably a good reference point (though I haven’t played Undaunted so not sure).
It’s pretty short, under an hour. It looks a lot like Chess but it isn’t as similar as it appears. Units have movement or attack abilities that are way simpler, more consistent and less dramatic than Chess. You draft units at the beginning of the game and which you get will have a really big impact on how the game plays out.
A lot of the strategy is deck-building / manipulation focused. Often what you want to do is create a set of tokens where you can activate the same character consistently every turn. Other times you’ll be running 2 or 3 aggressively. A lot of the strategy comes from counting what’s in your deck and discard as well as what’s in your opponents deck and discard so you can make decisions about where you’re likely to have power for the longest. Like: if you see all of your opponents left flank tokens in their discard, now’s a safe time to put yourself into a dangerous position on their left flank, setting up a strong attack next turn.
I played the game with a bunch of people and only a few of them liked it, unfortunately. Whether you like doing that card counting and drafting an army seems to be a big determiner in how well it goes over. I personally loved it because I’m a big fan of those mechanics.
