But for those that actually like using their brains on and off the computer quiz games can be fun.
Whereas I know that some players like sitting in their rooms all day on their own, I get my mates round, with a few ice cold tins of beer and play banterous games that include everyone.
Quiz games usually fit into that margin... the more they make, the more chance there is of a few good ones being about, and the more that my real life friends and I can play socially.
