Advantages to starting over: More players and the chance to rework or add elements to the story you'd like to see different. More probable players. A fresh start.

Advantages to continuing: You already have, at least it seems this way, dedicated players who want to see the end of this journey. What's currently established isn't broken, so no need to fix it. We're already along in the story; we wouldn't need to back-track through the intro if we simply continue.

Personal Opinion: I'll flow with whatever you decide. A part of me simply wants to continue but another part of me wants some slight changes that I can't put my finger on. One way or another, I'm with this RP till it actually dies or it is complete.
