It's your mother's 60th birthday. The big one. And you're running late.
The Birthday is a solo or duet ttrpg about family¸ relationships¸ and obligation. In it¸ you (and your sibling if you play with two) try to survive the mammoth event that your mother's birthday has become¸ do your best by those you love¸ and escape unscathed.
To you¸ your mother's birthday is like one big familial mapcrawl. As you move from room to room in your mother's house¸ you'll roll dice to see what conversations befall you and how your festive evening will progress.
