I think RDR is one of the few games that makes me regret being PC only now. I realize it's an old one but I didn't get around to it back in the day. Other ones are probably Uncharted 3/4, The Last of Us, and Bloodborne.
Last of Us is the only big one for me, but that was easy to solve. I borrowed a friends PS3 and played it something like 2 years later at the end of the PS3's life. Done. Will do the same with Last of Us 2 and PS4 in several years no doubt. These games that I tend to like on the console are all things that I can enjoy as a one and done type thing, so they rarely feel like a massive loss, but are still things I usually get round to several years late. I think in total so far, there is RDR, Last of Us 2, Bloodborne (maybe), Last Guardian (though the inside track seems to suggest it won't be that great, so maybe not)... that's it. MS has pretty much nothing I care about thus far. Nintendo is pretty much where a lot of games I like are (first party) but they have become very easy to miss out on after years of only using the platforms on and off.
