Demon's Soul
Demon's Souls is an action RPG which pits you against the forces of The Old One as you fight to save humanity from extinction.Released in Japan on Feb 5, 09.International release TBA
Final Fantasy XIII
My impressions are;the story sounds great,a female main character named 'lightning' is an interesting idea,the world looks beautiful and interesting,the graphics look incredible.The battle system will bring back the ATB system and add things that are new.And the summons will have a more mechanical feel to them eg Shiva will return and takes the form of a pair of sisters who can merge into a motorcycle, which the character Snow rides, and can use ice to create a path to drive on.Release date in Japan in late 2009.
