Since I haven't done this at all...
Customer Service - 8.50
While they are very helpful and will do much to help out anyone in their means, support tickets don't have much use. Well, I don't know about now, as I haven't used one for quite a while now. But, I know that before, it just worked faster if you e-mailed their store, or called them.
PR - 6.50
They do a really good job about letting us know stuff about games and present it in a great way, but their information usually gets spread via a separate site (Siliconera), and that kinda makes it feel like their own fanbase on this site isn't as important as the Siliconera users. It's getting better, but I really would like being the first to know, rather than having to read it off a link posted off a different site.
Localizations - 9.00
I consider them one of the best out there. The only qualm I have is that we have yet to see how well they can handle a truly serious game. So, I can't give them a 10 until I've seen that. (AT 2 is done and over with, so I didn't even take that into consideration, only what they've done recently. I also haven't played Prinny 2 yet.)
QA - 9.50
Their games still have bugs, but that's mostly the fault of the original developers. Still, it is cause for concern, so a 10 cannot be given.
Community Interaction -9.00
While they may limit their community interaction on the forums to pretty much just Lyner and Robbie (with Lyner being the one who gives the most interactions. Robbie just mainly answers PM's from what I've read), they do a great job with it. And on the Playstation Blog posts and other site posts, they interact a lot and answer many questions. You don't get that from many companies anymore.
Overall - 8.50
They have their problems like any company, but they have shown that they're listening to us (Lyner confirmed that Neptunia was the restult of fans showing enough interest =^-^=), and they are quite informative about things. They also go out of their way and comfort zone to help us often times. Some may not be happy with the Neptunia situation, but I think they handled it the best they can. No one can prepare for Nature. As I said elsewhere on here, nature can cause more damage than an atomic bomb, and be more unpredictable.
(Keep in mind this is only my opinion. You may disagree with it if you like.)
