I'm taking the reviews released today with a grain of salt, considering I've had serious issues with the gaming media this year (and to a larger extent, this generation) when it comes to reviews. I've hated several games the gaming media practically lined up to give blow jobs to (Bioshock Infinite, GTA 5, etc.), and I've really liked several games the gaming media practically set out to hate since the moment they were announced (Lost Planet 3, most of the lineup on the Vita, Sly Cooper 4, etc.).
While I'm happy that Killzone: Shadow Fall is reviewing very well (along with Infamous: Second Son, it is the game I bought the PS4 for, after all), I've felt like the media has had it in for Knack since it was unveiled back in February (IMO, because it was a cartoony platformer/brawler intended to appeal to children rather than a "serious game"). While I never thought the game would be "amazing" or anything, it's always looked like a solid game that would hit somewhere in that 6.5-7.0 range with the potential for more based on individual tastes. I'm not surprised that's around where it hit, and as I've seen scores ranging from a 5.0 to a 7.0, I think it's fair to say the game has some redeeming value that perhaps could extend into an improved sequel later on. I already have my copy, and I think I'm probably going to enjoy it, but I can understand why others wouldn't. At the very least, it's a new IP in a genre that needs new IPs, and it's a nice companion piece to Killzone.
I am pleased to see that Contrast and Resogun seem to be reviewing well as well. Contrast in particular seems especially interesting to me, even if it really doesn't seem like a game that "needs" the power of the PS3.
