Ive noticed theirs some interesting stuff on the subject in
http://wh40k.lexicanum.com/wiki/Main_Page#.UILin4aD9wE oldones, Demiurg, Galgs, Hrenian, Ji'atrix, Morralian, Nicassar, Tarellianthen theres other xenos empires and a whole list of chaos affiliated aliens i just wish some of these where more fleshed out in the fluff and game. After all how cool would it be to have a book of allies to call out for example chaos aliens like the Xenarch or playing as an eldar and tricking some Thyrrus into joining you and weakening your enemys. Not saying there should be a codex for each race but i guide book of lesser space fairing ally available races would make the
40k univers seem much bigger then just space marines and chaos no affence but
id like that over any new space marines chapters/ legions popping out. and having models would help me with makeing xenos as is the aliens i make for death watch could use some more verity. What do you guys think would it be an interesting addition to the game/fluff or am i the soul crazy man screaming at the invisible purple gnomes that steal my socks?
