I have an interest in military history (though I doubt I'm anywhere near as knowledgeable as many in this thread), though I lean more towards medieval history than more modern conflicts (WW2 being the only exception).
In terms of playstyle, I'd describe myself as semi-competitive. I'll take some fluffy options - especially on characters and will try to squeeze in at least most of the units I want to play (regardless of their quality), but I also try to ensure that my list is at least reasonably competitive.
I don't mind playing narrative games, or at the very least games with uneven objectives (e.g. a clear attacker and defender or one army trying to protect something and the other trying to destroy it; as opposed to both sides scrounging after vague "objectives"). However, since these tend to require a bit more organising, I tend to just play the standard games.
In terms of being behind, I don't mind when it happens naturally (one of my favourite games was when my
DE rolled horribly and ended up being overrun by Orks, with a handful of forces fighting desperately to hold off the tide), but it's not something I'd want to engineer by playing a terrible list.

I don't believe
40K is very suited to this - at all, thus why I don't enjoy
40K as much as I'd like. I'd actually 100% enjoy fake historical campaign books with pre-determined army lists (much as you get when playing historical scenarios in a WW2 game, etc.). My buddies always say "why don't you take this", and my response is "Well, story-wise, as I've developed this Renegade chapter they don't use or have access to those, or they don't worship that God, etc.). It penalizes me in games on occasion, but I enjoy the structure behind the game that's occuring almost more than the game itself.
Would you mind sharing one of your fluffy lists? I'm quite curious as to what story-based decisions you've made with regard to list-building.
