hmmm, distance aside, i prefer the official 3rd ed rules for dark sun.
I run a regular Saturday game during the evening and have 4 consistent players. We've had some players drift in and out, but for the most part we like to have solid, attached players that can make the time to join us a few times/month.
Right now we are running the Skull and Shackles Pirate adventure path in Pathfinder. We have just finished module 2/6 and so the characters are at about level 6-7. We would like to round out the crew with another couple of scurvy dogs.
We have also played a long Dark Sun campaign using 4th edition rules and we have played a Greyhawk Dungeon using 2nd edition rules. We may branch out into some other RPG's such as Dungeon Crawl Classics, the Rappan Athuk reboot by Swords and Wizardry, or the Dark Horror new release Shadows of Esteren.
If you are interested and live in the Ellensburg/Yakima/Wenatchee area and can make Saturday night games 2-3 times per month, we just might have a spot for you!
