The hardest part of any story is not deciding what to add, but what to subtract. I know from hard experience that it really, really is a
better idea to err on the side of "remove" here. When I first started Hybrid Theory I was just throwing bits in for fun, but later on this grew (and
BOY did it ever grow) to a major problem for plotting purposes. Later on, I learned a valuable lesson:
Only introduce a new character/plot element if you absolutely can not resolve your current story without doing so. This si epsecially true when considering
crossovers. The problem with a crossover is that you can't just introduce a single character form another story. Once you introduce say, Fate from Nanoha
you don't just get her you also drag in every character connected to her as well!
So my advice is to start as small as possible. Of course, if the premise is a multi-corssover on its face that limits your ability to minimize. Still its best
to be very thorough with one series before looking for new series to add, each one exponentially increases your workload!
