A colleague of mine writes a gaming column for another publication.  It's not a strategy column.  It mostly talks about what goes into inventing a table game.  The author should know as his name is Roger Snow and he's a Vice President for Scientific Games and heads up their table games division.  I've worked with Roger for more than a decade and together we've invented countless successful table games and sidebets.  Together, we've also seen hundreds of game ideas submitted from inventors.  There have been a lot that had merit.  There have been even more that have been absolutely awful.  But that's okay.  Personally, I find a bad game much more desirable than a bad attitude.
