I was actually a player in a Fireborn game a few years back, though it was not on Roll20. We played it every weekend for about six months straight so it was a decent length campaign for our GM (who was a first timer). What we found is that the game essentially asks for two different PCs from each player - one human and one dragon - and that it worked better if the two had almost entirely different personalities. Definitely discuss this with each player BEFORE the game begins and remember that it can be fun to play a creature that has no human morals! We dealt with a terrorist bombing attack in modern day - trying to find someone who'd stolen some artifacts from our previous hordes - while we relived an encounter with a wizard and his magical artifacts as dragons. You almost have to design two different plots to play in and find a way to force the memories to the surface in a way that doesn't halt gameplay completely. Our GM used tea and incense, playing it off as a "meditate to remember your past lives" sort of thing which eventually morphed into a game of chance anytime any of us was knocked unconscious or too relaxed (showers became hazardous as we sprouted wings while soaping up). It was very fun to play a dragon who cared nothing about killing to protect it's hoard and then come "back" to myself as a soldier suffering PTSD from a tour in Iraq. The guilt meant I had a lot of hesitation when it came to actually fighting the terrorists who wanted to blow a hole into London. I would suggest, if it's your first time running it, finding people who prefer story to rules. While the game can be pretty fight heavy at times, it works better if you have naturally inquisitive folk who WANT to know more about their past and how it plays in to today's life. Maybe the sort who like to play Call of Cthulu, but slightly less....suicidal. Maybe CthuluTech players if you want to have your players trying to hide what they are from the government. I'm betting it would also make a great war story, the super soldier angle works great when your players can literally breathe fire. I don't know if this was actually helpful, but I do know that Fireborn can be done, you just have to find the right group of people.
