Hot Gay Bro Dragons is a game about declaring your love for a hot gay bro dragon. The gender, orientation, and quantity of dragons are changeable, but the romantic declaration part is not.
Right off the bat, it leads with super strong layout and a gorgeous cover, plus some cheeky bro-dragon-related graphics. This stays consistent throughout, and the pdf is really easy to read.
Gameplay-wise, HGBD is more of a dialogue (you both go back and forth framing scenes) and less of a mechanical challenge. Honestly, it's probably even more accurate to say it's a series of affirmations, since the game directly says that it's less about telling a story and more about expressing love.
For folks who don't want to express love / have love expressed to them, this is a neat design and a cool game to read, but probably not what you're looking to play. For folks who really like both of the above, this is probably a thing you will enjoy playing.
Overall, I'd recommend this on its art/writing/concept alone, and it's especially worth a look if you're interested in romance rpgs.
