The PS4 looks to have more exclusives this year so far. Wii U is certainly not far behind it with their exclusives. I'm excited for almost all of them. XB1 is looking pretty bleak until after the 2nd quarter of 2015. I hope MS announces some great games coming.

All depends on tastes and personal opinions....
Some prefer, AAA, indies, RPG, FPS, platform, etc.

I see lists here that include PS3 games, so is that truly "exclusive" to PS4? Not trying to single anything out, but I did notice it.

Next post will contradict my initial statement. I feel Wii U has the most truly exclusive games that offer a nice variety. It's contradictory since its opinion, therefore I feel the whole question is difficult to answer with objectivity.

PS4.
It Has part 4 of my favorite gaming series of all time, Uncharted. Also, Bloodborne, The Order 1886, Until Dawn, Rime and so many announced games i'm sure. Like maybe The Last Of Us 2, Horizon, GT7 etc. If Silent Hills turns out to be exclusive too i'm gonna throw money at the screen until it comes out.

Honorable mentions though: Zelda (Wii U), Xenoblade Chronicles X (Wii U), Quantum Break (Xbox One), Tomb Raider 2 (Xbox One). I need an Xbox One and Wii U ASAP :/

While I think the games you mentioned(well XCX and Star Fox anyway) will be great.I have to ask why is it only "more of the same" for the PS4 and XB1 even though they have brand new games coming out this year like bloodborne, scalebound, no mans sky, the order 1886, Quantum Break etc but you named another Xenoblade game and another Zelda game for the Wii U. It just struck me as like well that's kind of unblalanced that's what made me ask.

Well to your point about the Wii U having the most truly exclusive games. That is kind of irrelvant to be honest because the question wasn't who has the most exclusives it was who has the best. While I do agree though there no is correct or incorrect answer because it all boils down to taste and the games one prefers to play.

Should have specified, most and quality are correlated IMO, should have specified. But like you said, no real wrong answers. 

PS4 easily with no explanation needed, esp if Dragon Quest comes to the west later this year. All Ninty has for me is Zelda. X1 has a fighting chance based on a possible megaton at E3 though. Im interested in Fable and stoked for Quantum Break. Their other titles generate some interest with me, but not as much as the PS titles.

And seeing how all of MS trailers put only on xbox on their exclusives, but went out of the way to say "only on xbox holiday 2015" I see this game going to PS4 as well within a year, so I dont consider it a TRUE exclusive until proven otherwise.

They may not be "truly exclusive", but they are as exclusive as Titanfall and FH2, which people didn't have a problem with last year.

Exactly. If a game releases on various systems... it's not "exclusive". Games like Persona 5 could be called "PlayStation exclusive" at best, but that's not the point of OP(which asks for platforms individually).

Missing PC but has Vita? Yeah right...
