I used to do 40K and Fantasy. Still have Necron and Sisters of Battle (though I think they're now called Sororitas) armies in their own cases but I don't think I'll be playing them anytime soon. At least two editions of the core rulebook have passed and I've found more intuitive games out there.

But I might paint up the remaining minis I do have. The best thing that has come from the experience is the painting and customising skills I have when it comes to repainting and repairing transformers.
