Matt here. I'm new to Fantasy, but not new to mini wargaming or GW. I'm thinning out my 40K collection and wanted to get into something new. I picked Lizardmen based solely on the looks. I'm not coming to Fantasy to powergame, but because my son wants to start Fantasy so I looked into all the armies and Lizards appealed most to me. My favorite 40K army is my Tyranids so aesthetically you can probably see the link. So hello and I look forward to learning your wisdom.
Welcome to the forum! Hope you and your son have fun! We got good tactical wisdom on the Tactics forum. I'd advise you give the Tactica Index a look. The painting forum is a good place to ask questions too. Whether you are a Picasso or a novice painter, you should received positive comments and constructive criticism.
Welcome to the Jungle. I am new to WHFB myself and I really like the look of the Lizardmen too. It is one of the reasons I picked them along with the background fluff.
Welcome, from one newb to another. We moved from the Hive to the Spawning Pool. I'm excited for zee leezards too!
Welcome! From one newbie to another, I'll tell you, there is a wealth of information to be found around here. The Tactica Index is a great resource, as Scalenex mentioned, and I've also picked up a lot simply by browsing army lists. Hope you enjoy your stay!
