NO WAI!!!
Yup 40K is what got me into writing - flipping through the Chaos section of the
Codex Imperialis and thinking OMGWTFISTHATTHING?!!! Then imagining the Horus Heresy and what the Emperor was like. Then I read the tiny entry about the Fire Hawks Chapter vanishing and BOOM! - first fanfic series I ever wrote. Super-complicated and super-epic.
So I painted up my own Fire Hawks Chapter, then got some Imperial Guard cos I thought "Hey! There's a challenge!", then collected and expertly painted a Necron army, cos... I had... plans... Wrote three new Codex rulebooks:
Codex Firehawks,
Codex Necrontyr and
Codex Crusaders (representing Ecclesiarchy rabble-rousing). Then I started writing up battle-reports when I played with my friends, exaggerating and hijacking certain parts of the battle so they would fit the dramatic arc.
Then my English Teacher noticed me doing it and said "Hey! Have your read Hamlet?". The rest you know.
And now all my models are collecting dust in my old bedroom.
