The armies I've collected, am planning on collecting, etc.? That's a long list, mostly Warhammer 40k and Fantasy.
I started with Tyranids and have a huge army that still grows occasionally, but has typically sat neglected on the shelf since the 6th ed Nid book came out. I've also had a small Genestealer Cult that I started kit bashing 12 years ago that expanded when the new book came out. A few Orks and Eldar here and there, and a decent size Chaos army I started working on a couple years back.
In terms of Fantasy, I started with Orcs, went on to Empire, Lizardmen, and Skaven.
My current projects are my new Basileans, my Free Peoples list for Age of Sigmar, and a few long term projects like finishing working on my Chaos and Genestealer Cult. Also, at some point I'll go back to my Seraphon and finish painting my Saurus Warriors and Knights.
I'll try to get some more pictures up in the next couple days. I finished the Phoenix and can post pictures of a couple previously finished models. This is a Lizardman site, so I should probably post some shots of my Seraphon/Lizardmen...
