We've been boardgaming for decades, but didn't truly discover modern boardgames till the mid 2010's. We got serious about the hobby and began really building a collection in fall 2016.
Workers placement is our favorite mechanic, followed up by deck building, push your luck, drafting, and engine building in no particular order.
Our least favorite is dungeon crawlers, followed by fiddly cooperatives (app driven co ops are fine.)
To us the asthetics, quality components, and table presence of a game are important, they enhance the enjoyment of a game (while poor quality components detract)
