As much as I'm into the aesthetics or production quality of board games, they're usually more of a "first barrier" that allows me to ignore a lot of the games that don't meet the right requirement. After all, there are way too many games out there that have both great mechanics and the pleasing experience created by great production. Still, a game's mechanics are ultimately what compel me to look into it and make me consider buying.
With that said: What are some new game mechanics you've encountered lately and what about them fascinates you? Plus, what is a mechanic that's somewhat commonly used but you've yet to try out?
I'll share mine in the comments.
