Lets pretend for a moment that 40K was like any other big toy line and you could go into toy stores and buy action figures.
I'd think that aside from Star Wars, you could produce the largest line of action figures from the 40K universe.
So as a thought experiment, what would your initial set of say 10 action figures be to draw in the kids and toy enthusiasts?
Here's mine:
Ultramarine Captain Sicarius
Chief Librarian Mephiston
Warmaster Abaddon
Swarmlord
Asurmen
Ghazgakhul
Grandmaster Draigo
Lelith Hesperax
Ursarkar Creed/Kell (combo-pack)
Commander Farsight
What's your list and why?
