I've had my PS4 since launch and I've played....

Favourites (Not in order)

-Assassin's Creed IV: Black Flag - Loved it!

-Assassin's Creed IV: Freedom Cry - More of the above but with a twist

-inFamous Second Son - Loved playing this, but so forgettable haha

-inFamous First Light - Fetch is so much cooler than whatever his name was

-Metal Gear Solid V: Ground Zeroes - AHHHHH METAL GEAR<3<3<3

-Final Fantasy IV: A Realm Reborn - This is where much of my life went

-Super Motherload - Best indie game on PS4

Meh / Haven't played enough to have an opinion

Least Favourites

-Mercenary Kings - Hated this for some reason

I need to look into Super Motherload. I was going to this morning but it looks like PSN was taken down again last night with a denial of service attack.

Favorites:

Infamous: Second Son

Infamous: First Light

RESOGUN 

Outlast

Don't Starve

The Last of Us: Remastered

Least Favorites:

Destiny

Mercenary Kings

Killzone: Shadow Fall

Meh:

Battlefield 4

Call of Duty: Ghosts

I have actually been most surprised with the indies. I need more meat in the long run though. Playing Knack now, have Watch Dogs and Far Cry 4 up next.

The smaller budget games are quite nice. I plan to get Peggle 2 before long as well.

Secret Ponchos is so, so, soooooo bad.

You need to play Transistor.

Favoriteses:

Shadow of Mordor

Diablo III

Injustice (I played it a lot on PS3 but still played it a lot when I jumped to PS4 )

both Infamous games

CounterSpy

Knack (I mean, it's not amazing, but I really enjoyed it)

Oddworld: New 'n' Tasty (fantastic remake of an already great game)

Need to play more:

Alien: Isolation (good atmosphere so far, haven't even played enough to encounter the Alien yet though)

Strider (like it so far)

Bound By Flame (okay so far but nothing special)

Rayman Legends (love it so far)

Child of Light (love the combat and art style, don't like the rhyme-speak)

Steamworld Dig (Better suited to Vita, where I've played it more, but great still)

Trials Fusion (fantastic so far)

Transistor (great so far, the combat sounded confusing in reviews but actually playing it, I love it)

Tiny Brains (fun so far but would be better with other people)

Least favorite/just meh:

Putty Squad (sort of borders on meh and terrible, somehow)

Watch Dogs (meh)

Need for Speed: Rivals (meh but the fact that you can't pause even in singleplayer is terrible)

RBI Baseball 14 (just terrible, or maybe I'm terrible at it, it's definitely one or the other)

Dead Nation (good with a friend, but I already played through it on PS3 so meh on the PS4 version)

I have a handful of other games that are either pretty good but didn't quite make favorites, or they're still in the "need to play more/haven't even started" category.

I don't think it's you. I was a big fan of the RBI series long ago. It seems they slapped this one together. I played it at a friend's house and thought it was pretty bad.
