Bought this when it came out. Utterly disappointed with it maybe played 10 or 15 hours and dropped it. Load of pump.
I liked it very much.
If I compare it to GTA V, GTA being the mother of the genre, Watchdogs wins the battle for me.
I felt that the non campaign content was much more interesting and entertaining than what I encountered in any GTA game I played (including GTA V).
There were numerous opportunities for awesome shootouts and this was much better done than in GTA V.
I also liked the main campaign and the world design was incredibly detailed and well done.
The gunplay was just excellent. The weapons felt really good.
I still remember the shootout on a highway I got into with dozens of criminals from two different gangs. It lasted for at least 20 minutes.
I only used a revolver that resembled the Chiappa Rhino and it was an awesome piece of kit (one of the best guns I ever used in a game). The sound and feel of it was incredibly satisfying.
There were downsides too. No game is perfect.
I would have liked to be able to use something like a helicopter for example.
I would have liked to be able to provoke random criminals and the cops to get myself into random escalating combat.
The population AI was too limited for that. I consider that a very big downside!
Many people complained about the driving mechanic, but when you got used to it, it made perfect sense for combined use with the hacking mechanics that are in the game.
In general I really like watchdogs and I had a better time with it than with GTA 5.
I played Watchdogs two times and am thinking about starting a third play through, just for the cool shootouts.
I never looked at GTA V again once I finished it. In GTA IV they had random mission generators, like the ripdeals. I still play GTA IV for that reason.
Stuff like that was never implemented in GTA V and that really diminished its replayability for me.
