Currently? Ummmm. Nothing. Well, reading some GURPS books while making a character technically, but not in any sort of commited way.
Been meaning to actually read Desert Raiders (by Lucien Soulban) for a while, may actually start.
There's something about the style of some older books that manage to hit the spot for description and newer books don't often hit that. This passage in Call of the Wild, for instance:
"They were all terribly footsore. No spring or redbound was left in them. Their feet fell heavily on the traill, jarring their bodies and doubling the fatigue of a day's travel. There was nothing the matter of them except that they were dead tired. It was not the dead-tiredness that comes through breif an excessive effort, from which recovery is a matter of hours; but it was the dead-tiredness that comes of months of toil. There was no power of recuperation left, no reserve strength to call upon. It had all been used, the last least bit of it. Every muscle, every fibre, every cell was tired, dead tired."
