Hello! Brand new here.
Based on first glance I have a suggestion. I noticed there was a Video Game section, and there were also "RPG" and "Retro/Classic" sections.
Perhaps "Video Game" can be a top forum, and "RPG", "Retro/Classic", "FPS", "Mobile" etc can be sub-forums under it? Not sure if this is already in the plans, or if it's even possible with this style of forums.
