Zelda fans when a reviewer scores Skyward Sword an 8.

Uncharted fans when a reviewer scores Drake's Deception an 8.

Final Fantasy fans when 13-2 is released.

I wanted to make this a poll but I don't know how.

If one can still call himself a Final Fantasy fan after XIII, then he will be raving with XIII-2 (aka not me) ;)
To answer your question - easily 2. And not just them, but the Sony fanbase on a majority basis.

An 8 for a Zelda game would certainly be pretty outrageous, but the Uncharted fanbase are probably more likely to actually act on it

#2

Well, there's no way Zelda will score an 8 (9.3 and above, baby!). So, Uncharted fans by default.

How does one game suddendly destroys everything for a Final Fantasy fan? Suddendly, Final Fantasy VI, Final Fantasy IV, Final Fantasy XII, Final Fantasy X, Final Fantasy IX, Final Fantasy VII dropped in quality or stopped being good games because FFXIII was a bad one? I'm proud to call myself a Final Fantasy fan, even though it's far from being my favourite RPG series and I will continue to enjoy FF games whenever they are of good quality.

Edit - I'm sorry if your intent wasn't on dissing the entire Final Fantasy legacy, but it came out across as that.

To rephrase that question, which fanboys react worse to negative reviews, Sony or Nintendo?

I would say that, in general, it's Sony fanboys. Nintendo fanboys are more used to seeing games get review scores below what they "deserve" (i.e. what was expected and what constitutes the user's opinion). So, Uncharted 3. Of course, the majority of reviews will probably be above 90 again, unless something goes horribly wrong.

I have used the term fanboys and not "fans" to distinguish between regular fans of a game and those who take it to a trolling level.

Zelda fans lol

Zelda Fans.
If they give Skyward Sword an 8.9, I'd be surrounded by rage, tears, fire and blood.

Zelda, the sony fanbase has become more tame.. recently.. notice how not many have complained with INFAMOUS 2/KZ3/and LBP2 reviewring poorly compared to AAA expectations...

but UNCHARTED 3 will likely score in the mid to high 90s on meta, the media is basically drooling over any bit of footage released.. it's like they're being payed to drool over UNCHARTED now

If UC3 get's an 8....then I will eat a giant sea worm. But yeah, Sony fans have been the biggest moaners this gen due to being in third place (even though they have the best console imo). PS3 exclusives like IF2, KC3, R3, M:A, GT5, SOCOM 4, Y4...are all less the 90 or 80 on Meta. UC3 needs to be a solid 90%+ like LPB2 but more so.
