Check out Imperial Assault Alliance. We are a very well organized star wars themed alliance, a democratic meritocracy if you will, and we value ambition and work ethic. If you have a talent and/or some energy you WILL get a position. Check out youtube for some of our videos.
If you are into guns and that sort of thing, definitely check out PUKE (a kalishnakov alliance), FINAL or Molon Labe. All three are pretty darn good alliances although I would recommend PUKE the most.
