The recent launch of Haunt the House and a visit to UK Games Expo where I picked up a copy of Spaghetti made me think about what family games are on the market and what distinguishes them from other tabletop games.
When creating a new tabletop game, a large chunk of time is spent on testing. Even very simple games need to be thoroughly tested to ensure they work. Playtesting helps identify whether a game is fun, balanced or swingy, lasts the right amount of time, works with the intended number of players and if there any issues with the rules.
If you have played a few tabletop games, you will have probably come across some that either don't quite fit your expectations or are a little ambiguous. That's where variants and house rules come in.
Every tabletop game comes with a rule book. Even the simplest game needs a basic set of rules. More complex games need longer rule books of course, but there comes a point at which a rule book becomes too long and turns people away from the game - and this point will be different for different people.
