I do not have a single Saurus in my collection, but the Seraphon are by-and-large my favorite army. They're just so darned nuanced. In my not-imaginary collectiong, I have some High Elves and Wood Elves I share with my wife. At some point, preferably after the High Elves are all painted up, I'll get me some Lizards. In my own hypothetical plans to expand into Seraphon, I wrote a guide to help me (and others) figure out what to do with the Start Collecting: Seraphon box. It's on TGA, and someone who's active on both forums recommended I share it over here since it asks most questions regarding along the lines of, "What do I do with this box?" My reply is: Get another box. I love the way Lizardmen look. I love the way Lizardmen play. I am especially fond of the variety of units, and ridiculous amounts of synergy.
Welcome aboard! Especially at the beginning, you can play an Order Allegiance with HE, WE and Seraphon, and (even if you lose the goodies of the race-specific allegiances) you will have some powerful synergies.
Out of the closets and into the jungles! Out of the closets and into the jungles! Out of the closets and into the jungles! Anyway, welcome to the forums! Let us know if you have any specific questions about game play, painting, modeling, or fluff.
Cool stuff, do you have a link to your guide? @Crowsfoot did something similar over in the painting section, I am curious what ideas you cam up with to do with the star collecting box as well!
