Dungeon Petz appears to still be at the prototype stage. It was demoed at Gathering of Friends, and is scheduled to be demoed at the UK Games Expo. It is expected to be released at Essen 2011.
Excuse me for saying this word on the Fort, but sounds absolutely adorable. It seems to have the potential to appeal to that generation of young gamers who grew up playing the various 'take care of your pet' e-games - Neopets, Littlest Pet Shop, Webkinz, and, of course all the DS Petz games. Since my house is littered with all of these, I'll be keeping an eye on this game.
Here's the description from the UK Expo:
Described as a game about breeding animals to sell off to evil Dungeon Lords, as all evil lords need a pet! The main principles of the game is the placement workers, which will then allow you to perform various actions (such as getting a new cage for animals, purchase of new baby animals, buying food, cure animals who suffered injuries). Each animal has specific needs which need to be catered for. The larger the animal, the more needs they have and the more difficult is to keep the animal in a cage in a pleasant mood.
Note: This is a stand alone game, NOT an expansion for Dungeon Lords.
