The target demographic is a highly sophisticated  group of game players. They play console games primarily, concentrating on games that require both hand-eye skills and larger strategic skills. This is true across all genres: sports, action and adventure.

Do not patronize these players. A trivial web game will  not only fail to hold their attention: It will also fail to gain their respect. They quickly recognize the six or seven ubiquitous Web games that are dished out by every advert-gamer: Point-and-Shoot, Slide-and-Catch, Memory, Trivia, etc.

• New skins do not make new games. (nor better games).

• Multiplication is not the answer. Four simple mazes or shooting galleries do not add up to make one good game. It is not that easy..
• Trivia games that obviously hammer in an advertising agenda runs a high risk of  alienatiing these players.

On the other hand, an approach that challenge real gameplaying skills earns a real respect that transfers directly to the Client.

Give them what they want.
