The work that Stormfront Studios have done in the past, most recently the acclaimed and highly successful The Lord of the RingsTM: The Two TowersTM, showed that they were the perfect team to bring all the action and intensity of the D&D® universe to the PlayStation 2," said Martin Spiess, Senior Vice President of Marketing, Atari Europe. "Forgotten Realms: Demon Stone is a fantastic looking game, offering an incredible gameplay experience made possible by a vastly improved gaming engine and innovative gameplay features. The ability to switch between characters while in the middle of intense action is a first for an action adventure game of this kind, adding a completely new dimension to the gameplay."

In Forgotten Realms: Demon Stone, the player directs a party of three characters – Fighter, Sorcerer and Rogue. The player controls one party member at a time - switching between them on the fly - while the other party members are controlled by the engine's sophisticated artificial intelligence. For example, when the player controls the Fighter, the Sorcerer and Rogue will continue to engage in combat, cast spells and assist the player in defeating all challengers. In many situations, the characters will be able to divide and conquer difficult objectives – while the Fighter holds back a horde of Yuan-Ti snakemen with brute force, the Sorcerer supports him with devastating ranged magic while the rogue sneaks above and behind them for a coup de grace. The player participates seamlessly in each critical moment as they are cinematically switched from one perspective to another.
