The attached sample video above basically explains the game writing process, what goes into the process and what needs to be done to make this process work in the scope of a video game project. Game writing is not as simple as it sounds, and I'm sure I have mentioned that before on this blog. Not everyone will approach game writing the exact same way, and we all have our own unique methods as to how we are going to reach from Point A to Point B in storytelling.
What you can take from the sample video is that the game writing process is indeed time-consuming, but with enough planning and teamwork, the process can be rewarding. Organization is one key thing that game writers will need to have in order to develop consistency on a game development team. Without any sort of idea as to what you're going to do make a story work, you are going to fail.
Most writers have a clear understanding of what the game dev team is looking for, and aside from that, the scope of the game story itself will need to be adjusted to fit the software that's being used to make the game. Yes, depending on what limits you have with your game-making software, the amount of story you can tell will be impacted.
Game writing will be a process filled with editing. Don't really expect to have every single nook and cranny of what you write to be accepted right off the bat. That's not realistic. At some point you will need to rewrite a certain scene or change a character's dialogue to better fit what is unfolding. Even if what you originally wrote wasn't all that bad, you can't get stuck on that. You have to make changes when it's really needed.
There are tactics to use when preparing to write a game script. When you keep in mind that a game script revolves around the choice of a player, it should become clear to you how flexible your storytelling needs to be. You don't just present one possible outcome to a situation. You have to provide a few possible outcomes that will make the player not only care, but keep coming back to exploit and figure out. That's why it's ideal to separate certain events and actions by writing them down on separate cards, which is what one interviewed game dev mentioned in the above video.
Your scope of storytelling can't be compacted. It has to have the ability to expand and branch out. That's what you need to let happen in the game writing process. You leave an area where your game story can build a bridge to another unique point of storytelling, and you'd be surprised as to how many plot twists you can take your game story if you just leave a bridge area open.
There are some interesting things to take from the above video, some of which I have already known about, and some that are fairly new to my knowledge. I recommend you watch some of the videos provided by the YouTube channel that made the above video.
