I have no problems with Ocean's two game@same universe... It helps you staying sane... All of those writers know what is writer's block... Having two stories helps you with than... When you know you're stuck, you concentrate on other game and without thinking, you can figure out what's the problem in first...
But Ocean has the first story complete in his head, not 100%, but he knows how all main characters from WIAB finish... Now is everything to make them to go there... In SG, those characters from WIAB are there, but we didn't had, probably, real contact with them... Teachers could play a story too... MC will go with Ayua in her dojo... We could there find bunch of old gang there... Or not...
