So a few things happened. Frog God does not own SW and I believe they are moving to make stuff for OSE. There was a split and Matt took SW core rules when he left Frog God games. The old adventures I believe are at Frog God Games still. (I am not 100% certain)
Second Potter and I intended to make this a general white box OSR ruleset and provide the content on the Forge. That is why you can toggle between games in the options menu and it actually changes the character sheet and rollers. At first everyone agreed to move forward but then Drivethru RPG language changed a bit with regard to exclusive rights non exclusive rights and VTTs. Basically these small game makers would have had to give up money to port their game on FG. Their DTRPG sales are >>> then any sales they would get on FG. So that's why only Operation White Box is officially supported and we never released White Star or Eldritch Tales. Although both should function on this ruleset.
Operation WB
I will continue to support this ruleset and if people have suggestions I will try my best to incorporate them. Both SW and OSE are similar in what they can do. OSE gets more updates because frankly more people play it and I get more feedback on it. I personally do not plan on making more content for this ruleset. However if anyone else wants to and publish it on the forge I will do my best to support it.
Hope this helps.
