Never played watch dogs so can't comment on that game...titanfall it was only game I played for the xb1 on a regular basis, now that Destiny came out haven't touched titanfall.
As far as hype I Destiny having the most because of playstation fan base and Sony advertising it like it's first party game and forum posts about how well the sales were on playstation compared to "x" game
Titanfall for me was a bigger letdown because the lack of story even more so then destiny
Titanfall multi player game just like cod really doesn't't matter if there is story...it's a game that holds it self based on a solid multi player
Destiny multiplayer is fun but not my cup of tea...ok with overall grind fest
