There is a Watch_Dogs giveaway now https://freetrial.ubisoft.com/promotions/watch-dogs-1/8/ I'm not sure if whether it's a full free game or if you will only be able to play it for a limited time
There are a bunch of articles on this. This is one of those: https://www.neowin.net/news/ubisofts-watch-dogs-will-be-free-to-claim-for-a-week-starting-tomorrow "Note that while the link says free trial, anyone claiming the game during the specified time will get to keep the game in their Uplay library forever." It's just a giveaway. Game is free to keep. Grab it while you can.
PC version can be made to b awesome, they have all the textures in the code to make it like the E3 demo, they just kneecapped it cuz of consoles.
That saying doesn't work when used with watch dogs, that's everyone's garbage, better just get some freeware games from the 80's or 90's over that pos.
