I liked Alpha Protocol. It was fun, and I could finish it on easy. It had colorful, interesting characters.
I think I would have preferred New Vegas over Fallout 3, if the Vegas strip had actually been bigger and more interesting. I had several quests go buggy on me as well. I probably relied on a guide too much and felt just strung along by the story as well. Wasn't much sense of discovery. The feel of being a rogue operator and turning all three sides against each other wasn't really succesfull either.
I'll protect everyone....with my TACTICS!
