>Be a girl
>Want to cosplay as a space marine for local con.
>There's a group of 40k players here who wear army supply shit and open carry and loudly argue about how manly 40k lore is all the time.
>Decide against it, I don't want to be shot at a con by raging fanboys.
Now I have all this foam and I need to find something else to do with it. Vaguely considering doing a Stormcast Eternal, since they're similar to Space Marines and some of them are women, but I'm not very familiar with Age of Sigmar compared to 40k so I'm worried about doing it wrong.
