My PS2 game library is my biggest collection of games at 180 titles. But even at that, it doesn't cover every letter of the English alphabet.  I'm missing "Q."  Plenty of "A"s, "D"s, and "S"s, but not a single "Q".  With all my other platforms, it doesn't even come close.  Do you have a collection of games for a particular platform that covers every letter of the alphabet? 

I'm missing a game with "Y" on my X1.
There only exist 3 games starting with a "Y" at the moment, but Yookay-Laylee will fix that :)

Are we talking about all consoles we own? Quack shot, sonic 1, and tommy lasorda baseball were my first games ever. Yes, i still own them. Anyway, off the top of my head....

I was literally staring at my boxes by the end of this.  I, J, U, R, and L were all difficult.

All or which ever ones you want to call out.  I was doing some reorganizing the other day and wonder with as many titles I have for the PS2, did I have a title for every letter of the alphabet.

I have all of them on the PS3. Rare letters:

inFamous
Quantum Theory
Vanquish
White Knight Chronicles
XCOM: Enemy Unknown
Yakuza 3
Zone of the Enders HD Collection

The closest would be my NES games. Missing O, Q and V.

Last poast was from my cell phone, lol.  I've been sleeping all day.  But now that I'm awake.  Turning on my PS3, I have

Undernight: In-birth,
Infamous,
Braid
Castle Crashers

Well... Nevermind. I'm missing y, and x on PS3.  I thought that maybe I could do it with a single console, but on Sega Genesis, I'm missing i, of all letters, lol.

NES. Must be an impressing collection. 

Well, I am missing Q, U and Z for my PS2 collection.
