My friend picked Adeptus Mechanicus as his first 40K army so I don't want to play the same army of course. Also all humans are basically a no-go for me. I hate their fluff and for me it is hard to completely ignore it. That's alsow why I don't want to play Space Marines, with the possible exception of Salamanders which - from a fluff point of view - seem to be relatively OK dudes compared to other Space Marines or humans in general.
Necrons.... Robot Skeletons filled with nothing but hate - although kinda cool - are not my style. I enjoy looking at them but I wouldn't want to paint them. Maybe play them, don't know since I haven't seen their Codex (or aynthing about their rules) yet.
Orks and the Chaos guys.... bah. Don't like how they look mostly, except demons because those just look as in AoS.
So yeah, Tau because I like giant Anime style robots. (Dark?) Eldar have those too IIRC but....fluff and so on... Tau are much more bearable for me. Nobody in that crapsack universe is a "good guy" judging by any meaningful standard, but the Tau seem to be fairly close at least. Well, sometimes. At least they don't mindlessly slaughter anyone including their own people permanently. The descriptions of Empire Hive Worlds or whatever those places where humans live are called make me want to puke. And the Emperor and his Government seem to be not only assholes but idiotic assholes not better than demons 98% of the time. No thanks.
Tyranids are OK because they are pretty much a natural disaster. They just want to eat everybody and go on. They probably don't even have a choice. Humans do. But they chose to be religiously fanatic, idiotic assholes.
So yeah not playing anything Empire, at least not until I have gotten used to the world a bit more. 40K fluff is really appalling to me most of the time. I would have to play them ironically and I am not sure I would have fun doing that.
I completely understand that, Had I played 8th I would probably agree. But since I have no clue who all the guys mentioned above are....any of those would have been as good to me as Alarielle (well, maybe not because Alarielle is at least a somewhat nice looking woman and I kinda like the Elf-wizard being reborn as tree-goddess-thing story).
I guess this thread quickly became a "all others" general discussion thread which seems to be popular judging by the number of posts in that short time.
