Yeah, most of those appeared on Games With Gold at some point, definitely been some good indie games, I just finished Superhot over the weekend, quite short but interesting.
Xbox Game Pass is pretty good for that too, its got Hue on at the moment (I haven't played it), I like a puzzle game, just didn't look/sound very good... but I might give it a go. I've been downloading loads of games from it recently - ReCore was pretty good, just started playing DarkSiders 2 - I already like how it fits into the first game and I downloaded theHunter: Call of the Wild last week - lol... was a bit precarious at first, it seems wrong hunting and killing poor innocent animals (rather than slaughtering humans in so many games I have) - but good news is that I'm absolutely crap at it.. its tough, I think I've shot 4 deer in about 4 hours playing it lol - the difficultly level makes the game quite unappealing - its more of a walking simulator than anything. But State of Decay 2 being released on XGP next week - looking forward to that.
