If the point of the GG section is to make tutorials, the place for it should be the already existing Modding University, while if you aim at releasing GG hacks, the place should still be Game Releases (where, if needed, I can add a new prefix named 'GG' or similar).
The reason I tend to avoid too many sections, is because it'd make everything a bit harder to be found, that's why I'm more into having a new prefix but still in the same section, rather than having a whole new section for something we currently have very few contents for, so far.
If, in the future, we should have a lot of interest into the GG topic, I might decide to separate GG content from the rest by creating a new section for it.
It's true we have a Nintendo and Playstation section, but it's a gaming platform, like iOS and Android which must be split to avoid confusion, but when it's about GG, the main topic is still Android/Modding/Hacking.
As per LP, while we do already have tutorials to help people get started to it, consider many users aren't willing to (or don't have time to) learn and/or mod games by themselves, that's why I strongly believe it's still important to keep releasing LP mods rather than just having tutorials to teach people how-to.
