If you need addictive flash games fill this form:
http://www.adultgamestemple.com/games.php and I'll setup an account for you to preview the games.
The games are do-it-yourself ones, you can practically change everything, whenever you want: the stripping pics, the interface, the rules, the back of the cards, the help file. They have a Top10 feature, you can very easy start contests and giveaway prizes such as monthly memberships, t-shirts...
They're sold under a lifetime license.
