I liked the first three. I never played Shadow Fall, but I heard it's okay. People appear to be assuming that these are games I personally enjoy or am looking forward to (not saying this is what you did/are doing). I'm just pointing out to the OP that there is plenty for players of all tastes on Playstation. Missing out on Halo isn't all too terrible when you consider all that the other consoles have to offer. And don't get me started on PC.
