The morality system and how poorly it's implemented.

Unlike the first two games where the decisions made in game during the quests actually affected the ending, the choices in Fallout 3 have no affect at all on the ending.  You could play through the game as an evil character; nuke Megaton, sell off people to slavery, murder entire towns, and just be a complete douche. Only to make the "good" decision at the end and get the "good" ending.  What's the point of having a morality system when all decisions in the game are inferior to the final ultimate decision? 


Mass Effect was just like this.  You could play through the game as an evil character, but the big major decision you make at the end of the game dictated the ending.  A good example of a recent game that implements a morality system correctly is Fable 2.  The decisions you make during the course of the game determine how the game plays and the ending that you get. (Mind you I haven't played Fable 2, but I have researched it enough to know this...correct me if I'm wrong tho)

Note: I still haven't gotten any of the DLC's (I'm waiting for my third and final playthrough to get them all and 100% of the achievements)  so I don't know how exactly Broken Steel changes the ending.  I doubt however that the ending will change that drastically. 

(When I finished the game for the first time, I expected to find out what happened with all the side quests after I finished.  There were so many questions left unanswered that could have easily been made for the ending.   What happened to Agatha? What if you decided to torch Harold, or let him grow?  Did the citizens of Arefu get along with the gang?  After Fallout 2's ending, Fallout 3's was a complete let down. )

Does this annoy anyone else?
