Re: Generic Living World OOC and RTJ for specific adventures
Either MidWorld or Clouded Paths look perfectly fine to me. I was even in Head in the Clouds, though I was not in TopWorld; but it looks like neither one mandates that there's character continuity.
I do have a concern that, if it is solo, Zerk is going to have a pretty hard time; after all he's only one character in the first place, plus he's fairly specialized, since I made him under the assumption that there'd be lots of characters around, so he needed to have a niche. On the bright side, since he's a droid he can be reprogrammed to compensate, to some extent; basically his skills and feats can be redistributed as necessary (and as money allows), which helps a lot.
