See I wonder since my estimation of online communities there are 8 Sony fans out of every 10 average users. Now since they will side with Sony no matter what, would Uncharted be considered the winner by default since its maker is really respected?

Because I can easily counter that Halo is a much bigger IP with a larger focus on MP and a sizeable following in its lore. 

Uncharted doesnt have a subtitle yet or even a legit teaser showing how the game will look or even a CGI trailer, so there will a bigger reaction to that than Halo 5: Guardians. Uncharted 4 could win E3 for Sony but it depends on how the game is presented, if anything like UC2 gameplay reveal or The Last Of US gameplay reveal then its done game. But i feel The Last Guardian can beat both of them, its one of the most anticipated games of all time, many gamers have lost hope so seeing trico alive would be a bigger deal. Nothing against 343i and Halo 5 but i see Quantum Break being the title that couls win MS E3.

But it is... 

"a view or judgment formed about something, not necessarily based on fact or knowledge."

It's literally the very definition of it. 

Considering the critical acclaim that TLOU received, it's not just his opinion.

AS far as sales go, unless something changes drastically, there's no comparison.  Halo sells quite well, and while Uncharted is more than profitable, it just doesn't move as many units.  I don't think it's likely that that'll change this gen, however, sales don't necessarily translate to quality.  I mean, I could point to any number of musical artists who sell absolute garbage at ridiculous rates.

Are you trying to argue what an opinion is? Everyone has preferences and obviously you dont like MS. I respect Naughty Dog because they make awesome games but I like MS Studios more. Not saying its a fact, definitely an opinion. Same as yours.

Halo 5 will be more of a big deal than UC4, obviosuly.

Also I don't get which people think UC is a massive IP, it's big sure, not more popular than GoW, GT or TLoU though and barely a blip on the radar compared to Halo.

Well games like those are so big that it's less about the reveal that they exist and more about the reveal about what's in them. As for who will win, regardless of quality, Uncharted 4 will win because the PS4 is what is on top right now.

So you're admitting that GTA V is better than TLOU because of critical acclaim? 

Oh....so you are implying its fact? Like there aren't anybody who would prefer a mega IP like Halo over Uncharted? Cute.

How deliciously smug.....you best be sure I am judging ALL Sony fans based on that comment :P

halo was a big i.p cuz bungie was behind it and lets not forget that fps was the most popular genre in US where xb360 pretty much killed ps3.

both games are a year off lets wait and see
