A friend and I tried two DS's with a demo version of Metroid yesterday. Smooth as silk. 3D graphics were better than I expected. Cut scene movies were nice as well. Really looking foreward to working on this new platform. Touchscreen worked flawlessly and opens up oogles of options for future game designs. (Just think of RPG inventories and stat sheets to manipulate by stylus) Control was like that of a PC FPS. Foreward/Back/Strafe was with control pad, aiming/turning/jumping with stylus. Firing with Trigger button. Also I see the Black and White spell system being used. (IE drawing out spell runes with stylus to fire spells. Enjoy.
