I am still on the fence with Titanfall. Paying full price for a game doesn't bother me, especially if I know I am going to invest 100+ hours on it over the course of a year. I played the beta and, I don't know, I think I was expecting more from the great return of West and Zampella.
I mean, when I played CoD4:MW for the first time, I was blown away. I didn't play many shooters and found them generally boring. MW changed that. It had an engaging story, with character development and a good plot. It was so much like a movie that you participated in. After the whole fallout with Activision and the creation of Respawn, I was expecting something to blow me away along the lines of MW. Titanfall just didn't do that.
A lot of that is probably just my own expectations. My high expectations were just setting the game up for failure in my mind. Plus, I am still very happy playing BF4, which is a massive time suck in itself.
That said, I will probably pick it up sometime in the fall. I still have BF4 to get bored with, plus I'd like to (finally) play through ME3 on Xbox.
