John cares so much for the players, as well as the experience he is presenting. He goes above and beyond to be flexible with the player schedules, and works even among his groups to coordinate when scheduling is difficult. Thank you so much, John! You are an amazing human being.

This is my first time I started playing D&D, and having a DM like John is like hitting the jackpot. John is absolutely excellent! I have a lot of questions about the game as a first timer, and he is very helpful. I am currently moving on to my 19th session, and I really enjoy playing John's "Vecna Unbound" campaign with my buddies. He makes me look forward to playing more and more every week. If you're looking to have a great time just chilling while also being on the edge of your seat as you're immersed in the D&D experience, I can't recommend John enough!

Me and some friends started an online campaign with John in January 2025. For most of us, this was not only our first time playing but our first experience with DnD. John is an excellent DM and Teacher. He is always encouraging us to learn more about DnD and is always available if we have any questions regarding, our character, campaign, or just DnD in general. His world building, character interactions, and fights are also top notch. His ability to adjust and play along with our choices is excellent and it never feels like we can never phase him or throw him off his game when we make rogue decisions. I cannot recommend John enough to anyone whether you are a new veteran player, John is the DM for you!

John is an absolutely incredible DM. From immersion, to patiently explaining rules and walking us through the character creation process, to creative adapting to our shenanigans on the fly, he really does it all. I'd give him 5000000 stars if I could.

This is my first DND campaign. John has an excellent way of showing us, new players, how to get used to the flow of the game. In both combat and RP he has a great balance of teaching us the tools our characters have to succeed while still punishing our mistakes which makes the gameplay exciting!

John's creativity, world building and attention to detail never cease to amaze me. If you haven't already, you need to participate in one of his games. You won't be disappointed! I first participated in his in-person games that he runs in our area and then joined in on this game that he runs on RPG club.

About

Hi, I’m John Kowalski. I am an author, freelance writer and editor by trade. I have been playing various TTRPGs starting with D&D since the late 1970s. Yes, my handle “OG Dice Jockey” is accurate. I have been a GM for most of those decades, including currently. My ongoing live D&D game has been happening for well over a year. I love the collaborative storytelling allowed by TTRPGs. My games tend to balance combat, roleplaying and puzzle solving. I accommodate all play styles, only asking that players treat each other with respect. Your characters on the other hand can do whatever they want, just be prepared for the consequences! Can’t wait to meet you and your characters! Let’s Roll!

This was a great game. I enjoyed the world building leading up the a ton of combat at the end. The GM was phenomenal at creating the setting and I followed easily with my imagination. So much fun, looking forward to additional plays with him. Definitely recommended as a GM, you will not be disappointed.

I've been playing with John for over a year in one of his in-person games. He is a masterful world builder who engages every character during each session. He does an amazing job of creating content that can engage the least and most experienced in our group. The details and story building that come out of the campaigns that he has written are impressive and always fun to play out!
