So Far Cry 5 has a free weekend starting Thursday (Tomorrow). Oh and it is 32.76 GB download, available for pre-download now on PC only.
here is the e-mail link i got from Ubisofts Uplay https://freeweekend.ubisoft.com/far-cry-5/en-AU note : i am unable to find it elsewhere atm so have a look around if you are not allowed to download load it.
