Aliens are probably THE most recognizable science fiction element EVER. And the fun part is that there are so many different KINDS of Aliens! You get alien horror like Aliens or Predetors. Hilarious aliens like 3rd Rock from the Sun or Earth Girls Are Easy. And your EVERYWHERE aliens like in Star Trek and Farscape. Not to mention how humans come across these aliens, be they visit earth for fun or attacking... or us encountering THEM when we travel space. How do YOU like your aliens best served up in sci-fi stories or roleplays?
