When writing this I'm really tired and need to sleep. So I will answer comments & make annotations tomorrow. I hope you will enjoy this playthrough, and I can clarify that I havn't played all of it yet. I'm about 80% done, and have been that for some time - want to buy time :) I plan to release these videos on a regular basis, once every 3 days I think. Making a unique intro for every video is what will take time, but it's worth it :)
