I am not a reviewer, but I feel really bad that no community members gave feedback on your forum.
The design quality is very vivid and realistic to your niche/genre of the forum. The design itself allows me to travel to the medieval times where most RPG settings are in. The music player in your header of the forum is a neat addition playing a variety of genres relating to your niche. I think it was really considerate that you set the music player settings to manually play music so you don't scare any members or guests.
The site structure is alright... I would want to inform you that you tend to have more discussion boards relating to general discussions rather than your niche. 25% of your forum relates to "RPG". The remaining consist of General and community matters (56.2% and 18.8%). Be careful, your niche can easily become more of a general forum overtime. I highly recommend to combine some forums together to balance things out. Combine your movies, TV and video games as Entertainment & Gaming. You can easily move the Literature, Entertainment & Gaming, and Music to "The Hub" board to make it more proficient. This will increase your RPG forums to 28.6% overal with 14 boards. This is just my personal view and you are not required or forced to change your board.
I wish you the best of luck with your forum! Never be too scared to take new risks or make mistakes. They will help you make many improvements for a better site!
Best Regards,
