This is my NeoHome. Read more for more info. I can help you w/ the following titles:
Smackdown vs. Raw 2009, Sonic and Knuckles Collection, Sonic Riders: Zero Gravity, Jak 3, Jak 2, Mortal Kombat vs. DC Universe, Burnout Paradise (A little bit)

Ok, so you know how I submitted Fatalities/Heroic Brutalities for "Mortal Kombat vs. DC Universe", well, they should be edited. So here's the rundown:

Scorpion: Fatality 1 - Down x3, Attack 4 (Sweep)
Fatality 2: Forward, Forward, Back, Down, Attack 3 (1 Step Away)

Sub-Zero: Fatality 1 - Back, Back, Down, Back, Attack 4 (Close)
Fatality 2 - Back, Forward, Down, Forward, Attack 2 (Close)

Kitana: Fatality 1 - Back x2, Forward, Attack 1 (Sweep)
Fatality 2 - Forward, Down x2, Back, Attack 3 (Sweep)

The Joker: Fatality 1 - Forward, Back, Forward, Attack 1 (Close)
Fatality 2 - Back, Down, Back, Forward, Attack 2 (Close)
Note: The Joker's second Fatality is a pain in the ass to perform. I learned that when you do the combination, you can hold Forward for about two seconds, then you can press Attack 2 (Triangle). It works!

The Flash: Heroic Brutality 1 - Back x2, Forward x2, Attack 4 (Sweep)
Note: All you have to do is walk up to the opponent and input the combination.
Heroic Brutality 2 - Down, Forward, Down, Back, Down, Forward, Attack 3 (Close)

Baraka: Fatality 1 - Back, Forward, Down, Forward, Attack 1 (Close)
Fatality 2 - Forward x2, Down x2, Attack 3 (Close)

Deathstroke: Fatality 1 - Forward x2, Down, Forward, Attack 2 (Close)
Fatality 2 - Forward, Down, Back, Forward, Attack 3 (Close)

Lex Luthor: Fatality 1 - Up x3, Attack 1 (1 Step Away)
Note: To perform this Fatality, press and hold L2 (By the way, I am talking about the PS3 version, so if you know the 3-D Movement button on the Xbox 360 version, then problem solved) and press the Up button on the D-Pad, then let go of the L2 Button and press Square.
Fatality 2 - Down, Forward, Down, Back, Attack 2 (Close)

Superman: Heroic Brutality 1 - Down x2, Forward x2, Attack 1 (Close)
Heroic Brutality 2 - Forward, Forward, Down, Back, Attack 4 (Close)

Sonya: Fatality 1 - Down x2, Back, Forward, Attack 1 (Far)
Note: FAR means walk up to your opponent, take ONE jump back, and execute the Fatality/Heroic Brutality.
Fatality 2 - Down, Back, Forward x2, Attack 4 (1 Step Away)

Shang Tsung: Fatality 1: Down x2, Forward x2, Attack 2 (Close)
Fatality 2 - Back, Down, Forward, Attack 3 (Sweep)
Note: Technically, you would have to be Close/1 Step Away for this Fatality. Weird huh?

Catwoman: Fatality 1 - Down, Back, Down, Forward, Attack 2 (Far)
Fatality 2 - Forward, Back, Forward, Back, Attack 4 (Sweep)

Jax: Fatality 1 - Back, Forward x2, Back, Attack 2 (Close)
Fatality 2 - Forward x2, Back x2, Attack 3 (1 Step Away)

Liu Kang: Fatality 1 - Forward, Back, Down x2, Attack 3 (Sweep)
Note: For this one, take about two or three steps away from the opponent.
Fatality 2 - Down x2, Forward, Down, Attack 4 (1 Step Away)

Raiden: Fatality 1 - Down, Forward, Down, Up, Attack 2 (Close)
Note: If you hold L2 while you do this Fatality, it will not work. So, in order for this fatality to work, get close, press and hold L2, press up, let go of L2, then do the rest.
Fatality 2 - Back, Forward x2, Down, Attack 4 (1 Step Away)

Kano: Fatality 1 - Back, Down, Back, Forward, Attack 1 (Close)
Note: Remember the trick for The Joker's Fatality? Well that trick should work. If you don't know what I'm talking about, then you need to actually FIND and READ The Joker's Fatality.
Fatality 2 - Down x2, Forward, Back, Attack 4 (1 Step Away)

Wonder Woman: Heroic Brutality 1 - Up, Back, Down, Forward, Attack 1 (Far)
Heroic Brutality 2 - Forward, Back x2, Forward, Attack 4 (Far)

Batman: Heroic Brutality 1 - Down, Back, Forward x2, Attack 4 (Far)
Heroic Brutality 2 - Down x3, Up, Attack 3 (Close)

Captain Marvel: Heroic Brutality 1 - Down, Forward, Back, Forward, Attack 1 (Close)
Heroic Brutality 2 - Down, Back, Down, Forward, Attack 2 (1 Step Away)

Green Lantern: Heroic Brutality 1 - Forward, Back, Down, Back, Attack 3 (Far)
Heroic Brutality 2 - Back, Forward, Down x2, Attack 4 (Sweep)

Note: For you gamers who have just bought this game or haven't figured this one out, even if you did figure it out, you would have to guess where to be.

Finally, those are finished. What should I talk about next? Oh yeah. Street Fighter IV. That game can be a pain in the butt, can't it? Especially when it comes to fighting Seth. But that can be solved. The trick is to learning his moves. He just does the same thing every time. Now you would think I would list the specials for each character, right? Well, don't think about it. That would take forever. So, now that I covered a little bit about Street Fighter IV, I have something else to discuss.

Sonic Riders: Zero Gravity -- Okay, now I know this game is a little old, but there is nothing wrong with talking about it still, right? So, if you are STILL trying to get Super Sonic, you have to get the EXTREME ranking for EVERY mission.But even if you do get Super Sonic, his style on this game sucks, to be honest. He really seems to piss me off on this game because of his style.

Jak 3: This game is fun to harass the citizens of Haven City. If you have all abilities unlocked, then you're going to have lots of fun. Especially the Dark Jak's Dark Strike. Only because when you use it, you can practically fling people across the city. Also, you can use the Dark Bomb the fling people also. If you don't have infinite Dark Jak, then you can use the RPG Blaster (The 3rd Mod of the Scatter Gun).

That's it for now.
