Avatars of War has just released a WHFB Lizardmen army list so you can play your lizardmen in Warthrone. If you want something that isn't as simple as Kings of War or Age of Sigmar but is different then 8th then give warthrone a shot. Rules are free, army books are free and if you have any questions the creator of the game awnsers them himself. For more info http://randomhit.org/2015/10/14/things-of-note-from-warthrone/ And here is the website to get started http://www.avatars-of-war.com/eng/web/index.php?option=com_content&view=article&id=59&Itemid=51
You should tell us a little more about what this is and how exactly it is different and post it in the Discussion forum
You've got a link to the lizard army. Can't see where I'm suppose to find them, from the links you provided NVM I seem to have found it
Yea I was going to put a link to the army up but it is a pdf file and I didn't feel it was fair to spring that in you
