How about writing up a Lustria Online carnosaur fighting game a bit like the Bretonnian Full Tilt jousting game. Where different Scar Veterans on various dinosaurs go at it in an arena fight, with detailed rules for different mounts.
I think Lizardmen would never do that. BFTJ doesn’t injure the horses. But Carnosaurs?!? Dinos are too much trouble to raise and train to expend them in that fashion. I can’t see how it would serve the Great Plan.
