Probably because some of 'em think it's a chink in the armor of the ps4 so they keep going after it. 

Remasters are optional and they don't eat up resources at all, if anything the sales of 'em give more resources to use with making other games. Fact is the things sell so until they stop selling, there will be remasters.

Why is Sony's first party line-up so poor then so far? Uncharted 4 is delayed as well.

Shoo! SHOO!

I'm pretty sure you're just trying to get a rise out of people now. Twice now you've avoided my counters and just tried to take potshots at Sony as if they've wronged you somehow. 

No, it's a fact that Sony's first party line-up hasn't been that great so far.

Littlebigplanet 3: glitched and bugged upon release, more of the same and also on PS3

Driveclub: online didn't work properly at launch, it's a racing game (too many of those exist already)

The Order 1886: short game, way too many QTE, mediocre gameplay, fancy graphics (at the cost of everything else)

Infamous Second Son: city is rather empty, good but unambitious game, more of the same.

Knack: unappealing main character, boring gameplay with unfair difficulty

Killzone: Shadowfall: a mediocre FPS

Bloodborne: their one true great game this gen.

MLB franchise: annualized sports games! Yay!

If you think this isn't disappointing then I don't know anymore...

During the same timeframe Nintendo released New Super Mario Bros. U (more of the same, uninspired, uncreative), Nintendoland, Pikmin 3, Super Mario 3D World, Mario Kart 8, Super Smash Bros. 4, Donkey Kong Country: Tropical Freeze, Bayonetta 2, Captain Toad: Treasure Tracker, Hyrule Warriors, Lego City: Undercover, Fatal Frame V (only in Japan) and The Wonderful 101.

I don't think you know what a fact is. I won't even go into detail about the rest of what you said because you're padding one side of the argument and ignoring the other (you sort of have to account for the rest of the year of PS4 games if you're going to list end of second year Wii U games, and list smaller titles for the PS4 if you're gonna mention something that sold as badly as W101).

I own a Wii U and most of the games you listed. The four I don't either aren't out here or are too expensive for my interest just yet (I have a backlog of 140 games after all, I don't need to spent $60 on another I won't play for months). You don't have to convince anybody that the Wii U has more exclusive games than the PS4; it should since it's had another full year of existence. If YOU have a problem with the console that's fine, but you don't have to let it seep into every discussion you have. After all, what's the reason to talk about how many problems the PS4 has in your eyes when it seems like you neither have it nor have any intention if having it?

Edit: The quoting must have messed up, I had way too big a quote tree than the rules permit. Fixed that. 

Aren't you forgetting that the WiiU launched 12 months earlier? So you are comparing 32 months Wii U vs. 20 months PS4!

So if you want to compare the first 20 months of Wii U with the first 20 months PS4, there are no Super Smash Bros. 4, Bayonetta 2, Captain Toad: Treasure Tracker, Hyrule Warriors and Fatal Frame V.

Wow the bias is real up in here! Sony has become a target in this thread. Everyone does remasters in one shape or another.

Huh? I just counted Wii U games from 2012-2014 and I counted PS4 games from 2013-2015.  I know there is still 4 months to go, but it's not like the PS4 has big first party games coming out this year. From the list I checked there's Until Dawn, Tearaway (Vita game with new stuff added in) and Everybody's Gone to the Rapture.

Next year is a big one for Sony though with Horizon, The Last Guardian and Uncharted 4.

If we're now only counting first party developed games, then you also have to chop off Bayo and the last four games from your Wii U list though.
