Usually sim games are light on charm and focus heavily on mechanics but Timberborn has both. 

It's sadly not a game easy to talk about, it's not like you have a cool boss or action sequence. Water goes up, water goes down, water gets polluted and your little beavers need to manage it. It's almost like a puzzle game involving water physics with a city manager glued to it. 

It's the kind of game I'd think Angie would love.
