Well lets see now. I know you've seen
Who Wants to be a Kommando?
(some fantastic fun in there) and
Give it yer Best Grot (Its all yours when inspiration strikes) but I can throw a couple more suggestions your way
I'll get the shameless self promotion out of the way first because, you know, I write ork fiction; grot fiction more specifically. So if you haven't seen it yet it's
The Adventures of Smirking: A Grot's Life I'm really very proud of that one.
And some of my top picks (in no particular order) from Dakka's own Ork fiction over the last couple of years are as follows.
A game of Bossgob by The Wise Dane
Da Book of Gork and Mork by Chazz Huggins (a collection of Ork Mythology)
Skrapmaster by Ossified
And this article from way back before my time here
Wurrzag Da Weird by Ein
I've only been here since 2015 so I'll be interested to hear any more suggestions from folks who've been here longer and remember good ones from way back.
