CoD: Black Ops 1 is a freaking masterpiece. It made me expect more from videogames and appreciate the little details. Then Ghost Recon: Wildlands and Fallout 4 were the first games that made me realize that an open world with such content was possible and the RPGs world. I know they are not massive, but I had only played in an Xbox and I had to be picky because I'm no rich. But yeah, I only have good anecdotes with those games and how impressive it was for me, mostly Fallout 4 because of secondary missions that had an impact on me, and then the other Fallouts which I'm playing in order right now and every one has its own impact, I love the franchise.
Extra: I love R6 and it was one of my favorites of all time, then I was introduced to the enshittifcation concept without knowing it lol. I kept playing Battlefield 4 rather than returning to R6.
