As someone who was Xbox360, I missed out on quite a few franchises (thankfully Sony did an incredible job with the UC & TLOU remasters on PS4) but I really would've loved to have played the Killzone and Resistance games, hell I think I was one of the few that thought KZ Shadowfall was brilliant... Holy fuck that opening is still one of the most technically stunning intros to a game ever, it just blew me away and really rammed home we where on the next generation, have yet to feel that way on this generation tbh outside of PSVR2, also Motorstorm looked incredible as well
