I've seen worse titles.
Anywho.
Yes, now to discuss ideas and such and such.
We can probably do whatever we want with this, it just depends on the starting tone. Some random ideas:
1. We start somewhere before Jack, after Father's Day but before The Empty Child.
2. We start with Jack in the group, but before the finale, probably between Boom Town and Bad Wolf. He's still around for more antics.
3. Same as idea two but instead of Jack sticking around, we let him leave so he can cross paths again later down the line. So he could be a minor roll as needed, depending on the antics we're up to.
4. A bit complicated, we start during season two, during The Girl in the Fireplace. During the window where Ten leaves Rose and Mickey with the TARDIS, she uses it to go back further in time, crossing her own timeline to warn the Ninth Doctor about the Daleks. Thus taking her own place during The Parting of the Ways in order to not take so much energy from the vortex that would cause him to regenerate when he kissed her. Or she could go back further, already knowing some of the events, could try and alter history while probably trying to keep her time travel a secret since it's a big no-no.
I do have a few more ideas but it would depend on what stuck out to you and what you're looking for. Usually when doing DW RPs, I find it best to follow say 4-6 small event "episodes" and then have a big event which could tie them all together, before repeating the cycle, in a sort of balance of big events and nice small ones. So for instance, if we wanted to see how Nine and Rose handled 42 or even Midnight, we could always redo them ourselves, if that makes sense.
