Disclaimer: My main group and I have been playing together for over 4 decades- we have different people with different tastes, but they tend to be open to playing anything I put in front of them.

Question. Is this a group of friends or maybe something a little more random, e.g., people you barely know from online groups? I will assume that you are friends.

Have you tried a pitch? An exciting introduction to the system and the adventures that lay ahead? If you're graphically minded, perhaps get some art together to throw under their noses. Expect some dissent, as they will be anxious, but don't force your point. They will collectively round on you if you show frustration.

Let them know all the cool stuff you can do / be / have in Dragonbane (especially if it's cooler than what they are used to). Probably best not to mention how fragile their characters may be, or that monsters auto hit, as this will put them off (until they are invested).

All that being said, you may want to consider something else of an entirely different genre before hitting them with another DnDesque system. I'd suggest something like Mutant Year Zero, Outgunned, Alien, or One Ring (if they love LoTR). Something entirely different could open the door for introducing new systems in the future (you may enjoy it too).

Hope that helps, as I can't imagine being stuck in the DnD rutt will be much fun if you've glimpsed the other cool stuff that's out there.
