Perhaps the title of the game is a little misleading. Actual Shivah (referring to the seven day period of mourning) is not a game and does not ever deserve to be described as such. But friends who are intermarried often tell me that they use historical fiction, for example, to learn about Jewish rite and ritual. So for a new younger generation, for whom video games and computers are as common as is reading, then maybe there is something here for them to glean in a new video game.
Here is how the creator describes it:
There may be something here for those interested in reaching out to the unaffiliated and unengaged - and what community isn’t? There may also be something for those who are looking to grow synagogue membership, since that seems to be a theme of the game.
