Fun filled and will take you away form your own life.
That alone made the game worth playing for me. I would deny nobody the chance to play this game.
You start off with the chance to customize your character to just about anyway you want. That starts off a whole trend of choices for a game that redefines the word choice. Also with all the choices you make (or dont make) throughout the game, they are carried over into the next mass effect game in which your save can be carried across. So the game does not end at the credits.
You can play through again with your same charcter and make different choices. Different romance sub-plots, and side qquests make this game interesting and attention seeking.
So thats just a small re-cap of what this game is like without giving away any real story line.
If you read this thank you very much.
