Tomb Raider is pretty cool, though I haven't played very far into it yet.
In addition to the bigger titles, some of the smaller games are great too. I like Don't Starve and Life is Strange a lot. Outlast was ok too. PT (the silent hill playable trailer) is pretty eerie and leaves me stoked for that game.
I wish there were some really huge hits that I'm super into, but there aren't many. There are some big games, but no really amazing ones and most of the big hits were originally PS3 games (GTA5, Last of Us).
I still haven't and would like to play Alien and Last of Us though.
I just noticed that there is a Star Wars Battlefront game coming out in November, I know almost nothing about it (literally just saw it in the PS Store), but that could be very cool. I'm also excited for Elder Scrolls Online and Witcher III looks like it could be cool too (haven't played the previous releases but they seem good).
Oh, and Metal Gear Solid V Ground Zeroes, that's a good one too. Kind of short but there's a lot you can go back and try to achieve/accomplish too and it's a pretty cool map/world you can explore.
