Mass Effect 2 Preview

Planet Xbox 360 has dished up a brief preview of BioWare's Mass Effect sequel, though it's more speculative than informative.
What made Mass Effect so popular in the first place was the cinematic story little information has been released concerning the Plot with developers keeping this very close to their chests as all that has been said to date is (Saren's evil army of Geth soldiers has just been defeated, and humans, who are still struggling to make their mark on the galactic stage, are now faced with an even greater peril). What various developers have said on the other hand is that players should keep their Mass Effect save files as decisions made in the first game will be carried over and will influence their characters in the sequel. This has the potential to change the face of the role playing genre and bridge the gap between the game and the player as the game continues the players story and will hopefully make each players experience different.
