I have ran pulp, black ops, modern and western, along with sci fi. I did not like the western game at all (it turned into a pulp game chasing down an indian mystic determined to raise an army of undead indians). I have no groove for cowboys; another evil rancher? Rob another bank? Yawn.
I prefer sci fi. If I run modern, I prefer modern over a military/black ops setting. However, even my modern games are pretty pulpy, with secret societies, aliens and lost magic inevitably turning up.
I have wanted to run a DOOM 3 sorta game since I played DOOM 3 and it scared the willies out of me a few times (if you play DOOM 3, play it IN THE DARK and TURN UP THE VOLUME. I promise it will make ya jump every now and then). Hell invades, and everything you were taught in Sunday school is true...what could be scarier than that?
