Hello! I am excited to be here. I played 40k pretty briefly around 10 or 11 years ago (I think 5th ed was new enough that no one I played with had any of the codices yet) and recently found some old models at a garage sale and decided to get back into it. They were mostly Space Marines, so I decided to start there. I would like to try Eldar and Tyrannid again, though, as I enjoyed them a lot before.
I will say that reading these forums has already been helpful for me to try to decide what to buy to get my army started. It'll probably be a while before I actually play a full-sized army, because I am not that good at painting (but I'm also something of a perfectionist) so it takes me a while to finish units and I don't even have everything I need yet.
I hope to benefit a lot from all of your wisdom!
