I've stopped adding material since I've rummaged through the OA website and the change in their policy prevents adding more recent material. Anyway, here it is in one spot for you to use in your SA campaigns.
This all started back in 2000 or so when I discovered Orion’s Arm. Yes, I am old. Deal with it. Anyway, I’ve been periodically checking out their progress over time – even looking in on their various projects, particularly the RPG project.
It seemed to me that they were set on a very quantifiable RPG, with every bit spelled out and defined in a manner not dissimilar to GURPS. Since at the time I was a serious GURPS fan, GM and player, this was very cool. Then the forums dedicated to the project disappeared under a tidal wave of porn spam. At which point I shrugged and largely forgot about it except for a few visits each year for a sensawunda fix.
Then in 2007 I discovered Sufficiently Advanced. I loved the hardish SF setting, with a rules set that accommodated a multitude of scales and really encouraged creativity by the players and GMs.
Somewhere along the way I had an idea: Orion’s Arm was absolutely full of material that Sufficiently Advanced GM or player could use. What’s more, I suspect the flow of ideas could go the other way, with someone using Sufficiently Advanced rules to play in the Orion’s Arm setting. That’ll be a project for 2009
Anyway, here it is – over 100 pages of a labor of love adapting a lot of different Orion’s Arm material to Sufficiently Advanced. I hope that those that read this enjoy it and use it in their own games as a source of ideas, and, maybe, some sensawunda.
