To provide some clarity about why you're not seeing as many modders or walkthrough creators for College Kings compared to other games can be broken down into multiple reasons.
- The majority of popular games have a simplified structure to them. For example, each episode in a game typically has only one script file and although it's long, it's easy to search through it for conditions, variables, choices, etc.
College Kings on the other hand, has a folder containing about 50-100+ separated script files for every scene in each episode. This means searching through multiple files at a time for a single condition, variable, consequence, etc. which is extremely tedious. On top of that, CK2's first episode is broken down even further into 4 folders containing about 40-60 script files since they slowly released the first episode in pieces. The developers announced that they plan on merging those 4 folders into a single folder soon, so any modifications to those files by a modder will have to be updated again after that merger happens.
- Following this, other popular modders add their walkthrough manually in the script files by adding "(+1 BRO)" or (+1 GF point) into the menu choices and upload the overwritten script files. As mentioned, those other games will typically only have a single script file for each episode making this easy to navigate the file for those conditions and add them. This is practically near impossible to do in College Kings though, since the amount of script files would be unbearable to do and would eventually have to be updated when episode 1 of CK2 gets merged into a single folder.
- On top of the script files specifically tailored to the story, there are a ton of other folders and scripts for other resources the game uses that requires navigating through in order to circumvent any conflicting issues. Most games usually have other script files for minigames, galleries, etc. but are usually more simple and straightforward. CK's on the other hand is all over the place.
- Finally, the game still has a ton of bugs they're patching which would also require frequent updates from the modder.
All in all, it's a lot for a modder to navigate especially one who is either new Ren'Py or Python alone to figure out the best way to attack these issues and a huge pain in the ass to any modder in general. Even creating a Walkthrough guide for people to read in a Google Doc is still A LOT considering how the scripts are broken down.
I'm still playing with it all on my own as I try to learn Ren'Py better, but with the amount of bugs, updates, and things that are currently being patched I have to question when is the best time to truly develop my own mod when the files are continuously being changed. At this moment as a novice modder who is still learning, I feel it's better to spend my time on other AVN's that are more simplified in order to develop my skills further before tackling a project like this. My university will also be starting again this upcoming month so my time will be more limited as well.
From my understanding, Duke is still developing his mod but I'm not quite sure if he's continuing his walkthrough portion he developed before that stopped around episode 2 or 3 or if he's focused more on a universal mod. Regardless, I recommend using his for now or another universal and just be wary of the variables that show up, create a lot of saves (you literally have 99 pages to save) and experiment. I know it's not the answer people are looking for, but that is the best I can recommend for now.
