Well given that achievment is largely predicated on time invested,
it seems implicit that those who tend to renew more will have higher
level characters. If you are inclined to cancel, then its less
likely that you will have high level characters, there are a lot of
opportunities to quit before then!

i.e. it could mean either :

   A) They won't quit because they have high level chars.
   B) They don't have high level chars because they quit.

So the cause and effect are transposed depending.

If you interpret it one way, you might erroneously assume that since
those with high level chars are less likely to quit, then you will
have higher retention by handing out high level chars to people or
lowering the xp curve. That may be true, but you can't reliably read
that from the data.

You might be able to extract further meaning by looking at hours
played as well, from a players perspective it is probably more
telling. As a company it is easy to get fixated on billing periods,
but when I play games I don't worry about that I worry about if I'm
bored yet.

That definitely supports the idea that looking at hours played might
yield more info.

In cases like this, it would be interesting to see when they had
last logged in & how often they died each level. Were these
forgotten accounts, accounts regularly played by socialisers, people
who made lots of characters but never leveled that far, or
incompetent players who just couldn't advance etc.

Your June conclusions sound fairly safe, and they no doubt supported
suspicians you held anyway?

Whilst I did jokingly suggest that you might hand out high level
characters, it is quite possible for DAoC that it might work. After
all there is a belief that the game is most fun when you get to the
high level RvR content which obviously requires a high level
char. Of course it would probably break other things :)

If you had wanted to know more, then an exit pole when people
cancelled might have helped too.

What that something is, however, is non trivial to work out!
