Before reading this topic, I highly suggest reading this guide first.
This is the most important part of your idea. If you look at The Lost and the Damned and The Ballad Of Gay Tony, you'd notice that both Johnny Klebitz and Luis Lopez were seen in GTA IV. When the DLCs were revealed, most people said "Oh, I remember that guy; I'd like to see GTA IV from his point of view." For your concept, you want to pick a character who was seen or at least mentioned in the previous games. That way, when people read about your character, they can make a connection with it and will become interested in learning more about them. Don't make up a brand new character, because even though it can be done, it seriously detracts from the purpose of a DLC and people won't be as interested in your idea. You also want to avoid using any characters who are mission givers, random encounters, or active friends, such as Little Jacob or Roman. This creates an inconsistency with the stories they are involved in and it just gets sloppy.
Below is a list of characters I and other members have compiled. They are the cream of the crop for possible protagonists, so it is highly advised that you use one! If you found a character who should be on this list, tell me and I will add it to the list.
|Seen Characters (highly recommended.)|
|Mikhail's bodyguard aka Sergei|
|Sergei from Comrade's Bar|
|Papi aka the unnamed dealer|
|Unnamed dealer from Shifting Weight|
|Unseen Characters (from LCPD Database.)|
In TLAD we witnessed the politics and workings of outlaw motorcycle gangs, which was something we hadn't done before. In TBOGT we saw the glamorous nightclub side of Liberty City, which was also new to us. Try to establish a theme for your concept, whether it be oriented around a gang or subculture is all up to you, but it should infect everything about your DLC. The weapons, vehicles, and missions should be a product of the theme you established with your story. For example, in TLAD we were given new, gritty weapons and motorcycles to reflect the theme of a bikers tale. In TBOGT, the missions, weapons and vehicles were ridiculous and over-the-top to manifest the theme of the DLC.
This is what makes a DLC topic interesting to follow. In TLAD and TBOGT there were crossover missions where the protagonists from each story actually met in person more-or-less, like the diamond deal. Your story should have at least a few well thought-out crossovers. The objective with a crossover is to explain unanswered questions or see an important event from another perspective. You want to avoid crossovers that are far-fetched or don't accomplish anything. If you force a crossover that isn't very plausible, your story loses a lot of its credibility. Just build your story in the right direction, and if you see the opportunity for a good crossover then try and make it happen. Not every mission should be a crossover; that just shows that you lack the creativity to build your own story and you have make your missions off of the backs of others.
Some DLC concepts actually cross over with each other, such as Code Of The Streets and Blood And A Four Leaf Clover. If you and another member are interested in connecting your stories, PM each other and establish some cross overs. Make sure the other person is willing to cross over with your story before you start putting their characters in your story! You can even make it official and create a topic akin to Episodes From Liberty City, only it involves both of your concepts.
You don't want your whole story to be about your protagonist merely doing jobs for money. He should have some sort of goal along the course of the story. You can include things like the diamonds or the heroin, which were both used as tools to bring different characters together under certain circumstances. There are a lot of things mentioned in the story that could be used as plot devices, and you can even make your own. In my DLC topic, Blood And A Four Leaf Clover, I fabricated a plot device in the form of a priceless painting that shifts hands throughout the story and is involved in several missions. Things like this help give you a direction for the story, and often provides you with ideas for missions that can involve them.
DLC topics may seem easier than full-game concepts because they don't require a lot of the same content. All you really need is a story, weapons, vehicles, etc. to make it happen. However, you should at least take the responsibility to describe how the whole story unfolds by posting individual missions. Your missions should be detailed and well written, regardless of your writing skill. Take the time to make sure the grammar is all perfect and the cutscenes can be visualized by other people. Try to include some dialogue that helps develop your characters, and some humor here and there for that GTA-touch.
More importantly, make sure each mission is innovative in terms of gameplay. One of the flaws of GTA IV was that fact that nearly all the missions were "Go here, kill these guys, chase this car, etc." Try to give each mission some kind of gimmick that it will revolve around. For example, you could introduce a new weapon and the mission would involve using that weapon's certain abilities. Don't just create a sea of missions where you are just senselessly assassinating people and crashing drug deals between gangs; bring something new and interesting to the table with each mission.
A clean visual presentation is what will make your topic one of the best. No one likes to see, let alone read, a boring wall of text. Use tables and graphics to spice up your topic. See here for creating tables and put in a request in the GFX section for a logo, headings, etc. Another great perk of a DLC concept is the fact that you can get in-game screenshots from the original game. If you don't have the resources to take screenshots, you can ask someone who has the game to capture some screenshots for you like The Lolwut Pear. But remember, all the graphics in the world won't matter if you don't have some quality content in between it.
