What are your favourite aspects of this hobby?
Even sticking to historical accuracy and being something of a rivet counter, I find it absolutely amazing how creative you can get with this hobby in so many ways and I find it remarkable how multifaceted it is.
One of my favourite things is finding a historical TO&E and then adapting it into a list for Bolt Action in a way that is viable to the game but still pretty true to history. In the course of that, the historical research aspect of the hobby also provides loads of fun and inspiration for building your list and your individual soldiers from the Warlord kits. From reading primary sources such as battalion war diaries, you can also get inspiration for different scenarios too. Plus, reading military history in general is just something I like to do personally.
Collecting is another thing I enjoy: I love being able to mix and match from different manufacturers to make my army my own. I find painting pretty straightforward but basing to be another area where the creative juices get flowing. I haven't really done much playing but I consider it to be the cherry on top!
