Also Heavenly Sword, Resistance, Motorstorm, Ratchet & Clank and Folklore.
Heavenly Sword - universally panned
Resistance - generally regarded as an average to middling game by all who didn't play it (i.e. most gamers)
Motorstorm - unfortunately niche gem. A cracking game that was far from a hit
Ratchet & Clank - probably the most successful outta the lot here
Folklore - fanstic game, but niche and not very well received by the media who didn't understand it.
All not very high scoring games (bar a couple of exceptions), or in pretty niche genres if you go by their metacritic scores. None were very talked about at the time, and none really did much in the way of selling consoles for Sony or impressing gamers.
If the above was the current slate for PS4 now, this thread would still exist.
I don't think Sony's problem is that they haven't taken risks, the problem is that a lot of the games they released were not really best in class. A lot of them weren't necessarily bad, they just weren't as good as the hype and probably didn't catch fire the way Sony wanted them to. They have a varying degree of success with their big budget exclusives, but for the most part I'd say they're not putting out hits with the exception of a few obvious titles like Naughty Dog games.
If you're only talking about Sony's retail AAA-budget games then sure, but I'd argue that even then they probably have more hits than the majority of other big publishers (if by hit we mean >3m unit sellers). Outside of GT they don't have any mega-hit games (i.e. 10+m sellers), and I think that's where this perception comes from.
Few pubs put out more than one particular game in any genre that is "best in class". And I'd argue that Sony has more BIC games than most pubs. It's just that the "classes" in question are not the most popular, biggest selling anymore (e.g. racers).
In terms of hit games across AAA retail and download, I'd say Sony generally delivers the goods. In terms of quality, they've certainly produced alot more interesting and enjoyable games for me personally than any other publisher. They also have one of the most diverse portfolios of any gaming publisher, which I think contributes to alot of the failures and turkeys they've put out on the market, but also alot of the surprising successes, both critically and commercially (e.g. Journey).
