A free app for Android, by Palmnet.
There are many great card games out there, but there are none that have been designed with the player in mind like this one. The idea is to give the player the tools to build their own cards. They can choose from a variety of card designs and backgrounds, as well as choose their own game theme. Once the cards are built, they can be played in a variety of different game modes, including single-player, local multiplayer, and online multiplayer. There are even tournament modes for those who want to compete with others for the best cards!
The game also has a unique, non-card based gameplay system that allows the player to interact with their environment, allowing them to destroy and build resources, grow plants, raise animals, etc. The game is based in a 3D world that can be explored by the player.
