Titanfall: Expedition adds three maps that enhance the Titanfall experience, but adds nothing for those who are already tired of the game. If you just want more Titan vs. Pilot action then this is perfect for you, but all others should keep an eye out for the free updates coming from Respawn.
Gods Will Be Watching is certainly a unique experience, but that doesn't make it an interesting one. It relies too much on random chance and does nothing to compensate for the frustration that will cause. Unless you enjoy punishment you might want to avoid.
Dead Rising 3: Apocalypse Edition offers an improved experience on PC, but it is held back by some of the same problems that existed in the original game. If your PC is powerful enough to run it at full speed then it is an enjoyable experience that is worth checking out.
Destiny offers a lot of promise, but ultimately fails to deliver on everything it attempts. Still, thanks to Bungie's fantastic FPS design you will have fun playing the game. How much time you are willing to put into it will largely depend on how easily you get past the repetitive missions and maps.
