Watch Dogs or AC:Unity (PS4)

Hey, I'm thinking which of those 2 to get. I'm kinda stuck so was wondering if you guys can help.

i don't know really know man, they're both really great games, if i had to make a decision I'd probably get watch dogs. (but i guess you probably would have guessed that that would be my choice because of my username)

If you like history, then go for ACU

If you like doing free roam, hacking go for Watch dogs..

If you like history,bugs and glitches go for Unity.. xD

@vicky_john1: How is the online in these two games? Any good?

Yeah I'm thinking about the longevity of both games. I heard AC:Unity has quite good multiplayer... anything to do in Watch Dogs once the storyline is completed?
