I can answer all questions in the sub-categories of World of Warcraft, Runescape, Call of Duty series, and some Roguelikes, I've had experience with these sub-categories for years now. I have the most experience in World of Warcraft but, I have high knowledge in Runescape, and Call of Duty. I would be glad to answer all questions under these subjects as well as to dive into other similar games if required.
I've played these games mentioned above (World of Warcraft, Runescape, Call of Duty, and Roguelikes) for many years now and have seen a lot in all of them.
there's sadly no educational credentials I have for video games.
