@xianc78 I tend to prefer option B, just because I feel it lends the series less rigidity and more towards experimentation with subsequent entries, keeps things fresh, if only on a surface level. Also it gives each character the ability to have an arc with a definitive "end," even if they end up being a supporting character in a subsequent entry their role in that story could be completely different (plus you don't run into the problem of "character fatigue," as easily).
