Code:

Insert ending here

Mass Effect 3:
Ending had some plot holes. I didn't extremely hate it like others, but I still understand the points they made. It's not Biowares finest hour but the games from the beginning of 1 to (pre-finale)3 was great. Just the ending was a letdown
Borderlands:
Completely pointless. Luckily for Gearbox they managed to save themselves with the DLC(Claptrap's New Robot Revolution) to make the ending make sense.
Final Fantasy XIII-2:
Didn't even have an ending. It's DLC...still not been made
The Conduit:
...I don't get it.
Condemned 2:
The game went down the crapper during the second act. So the ending was naturally bad.
