In a recent interview to the magazine GemeInformer, Sid Meiers spoke
XCOM: Enemy Unknown , explaining how in one game he tried to mix strategy, action and RPG elements. The idea is to mix together different genres and allow players to face the adventure from the point of view they prefer: there will be those who start on a more tactical approach, who is more aggressive but everyone will enjoy every facet of the game. We are waiting for new info and pictures on the gameplay.
