Sony Worldwide Studios' Shuhei Yoshida has expressed his disappointment over low scores following the reveal of reviews for PlayStation 4 launch titles.
Yoshida offered his explanation for the critical response, stating online functionality on PS4 was only recently working, and adding that reviewers likely had to play through the games quickly.
"I haven't spent enough time reading reviews, but I would characterise them as mixed," Yoshida told GamesIndustry.biz.
"And with this launch there are lots of games coming out, so the media must be very busy going through the games quickly, and especially since the online functionality wasn't ready until in the last couple days. So we have to look at how much time they spend on what aspect of the games and how that may be contributing to some of the lower scores."
He added that despite these scores he is not worried for the new console.
"I'm now on my second run of Knack and Resogun at a higher difficulty - these games really grow on you when you play more. I'm very confident that once you purchase these games and play, you'll be happy that you've done so."
Knack received a 6 out of 10 review score from Polygon, while Killzone was rated a 5 out of 10. Resogun received an 8.5 out of 10 score, in a review that stated: "Resogun is a collision of 1980s shooters, 1990s bullet-hells and 2010s aesthetic. It's as simple or difficult as you want it to be. Sure, it borrows great ideas quite liberally. But Resogun's best idea is smashing them all together into a singular, spectacular laser light show."
