Tope, I am very very grateful to you for starting this wonderful thread!
I've been an MK fan since I was a little boy. It was because of Eddie Boon and John Tobias that I even studied Computer Science in the very first place!

I like Rayden the best.
Why?
Well, basically because when I'm controlling him NO PLAYER ON PLANET EARTH CAN BEAT HIM, that's why.
That's an open challenge. I dare all of you players out there.
If I've never boasted about anything; I'm boasting about this.
Nobody can beat my Rayden!
Ritchboi,
Yes. People still play MK.
Yes. Some of the best programmers on planet earth are still busy from dawn to dusk improving MK with new and better codes, graphics and concepts.
Yes; God made man in his own image and likeness.
Man made Mortal Kombat.
Hey, Sniperwolf! I take that very very personally!
You have insulted the God of Thunder.
(I'm going to ThunderClap that a**!)
You're the best player, you say?
Do you want me to come over to AJ?
Omo, I no run!
Make we try am?
Or should I just let Mdsocks do it for me?
Nna, take time o!
Gamine,
Rayden doesn't need cheats to humiliate you -- whichever player you use!
If you're going to cheat; desist from using Rayden!
Use one of those other weaklings in the game -- but stay away from Rayden.
Period!
Oyb,
Jade is a p***y.
Face me.
(I know you've already figured out exactly what it is that I'm going to do with that stick you're holding!
Ha!)
Kempest,
Yes, the unmasked Subzero is goodlooking.
He won't be looking good when I'm through with him, I can assure you of that.
Which version? Which console?
Showbobo,
Learn to use Rayden.
You haven't even started to play MK.
Shio!
Migines!
You're my man!
You've used the Thunder God on MK4?
Which console? (I'm guessing PC.)
He's the best.
When I used to play that; I used to be airborne from the beginning to the end of the match.
Nobody can stand that kind of action.
I'm the bestest of the bests.
Believe, friend!
Ravenzord,
That Kwanshi guys was a badly developed character.
He's small potatoes.
Block his stump -- and send him back where he came from.
Or block; and then show him the wrath of a Combo-King!
Who you using anyway? Huh?
Iice,
You're a king, King.
Raiden is the best.
Forgot those other players you mentioned. They're fertilizer!
Mdsocks!
I want to send you money!
Yes! Rayden is the best.
Thank you! I love you, King!
Thank you!
Cooljoe,
Cash rules everything around you save your thinking cap.
How can you place such faith in such a limited player?
Scorpion's timing is all wrong.
When he's shooting s*m*n out his palm; he's as vulnerable as a newly born child!
He shouldn't even be in Mortal Kombat!
I'm going to meet you someday and prove that to you, Joe.
Watch out!
Dejavhu doesn't know the definition of Old School.
(Not to mention the spelling!)
(Hey, don't MODIFY that!)
MK is a classic. All of them.
If you play them, you'll understand better.
They are all different and all special.
It's the players that suck!
Justbones is just learning to play.
He likes Ninjas.
(Can you imagine that?)
