Trevis summed it up pretty well with his post. I tend to agree with much of what he said, and said so well, especially this part...
The collector part comes from me being somewhat of a completest. I do not collect for investment purposes. I collect because I like to have various iterations of something, because of the art, the story, the originality of what it was when it first came out.No other creator or book presents a more satisfying character and overall positive reading experience than Usagi.
Twenty years from now people will still be reading Usagi... ...Usagi is a constant, consistent and timeless property. Everything else is a distant second place.
That's why I collect the singles. I started fresh with the Mirage series when it was published and haven't stopped since then. It took a little doing, but I eventually acquired most of the early issues, as well as some odds and ends (thanks to the help of Dojo members).
I collect the standard TPB's and have all of them. It wasn't until late (2011) that I decided to collect the HC. I recently was able to complete the task and have now acquired all of them.
In regards to the Saga series, I only collect the HC's.
I will also collect any other HC's that are released.
Like Trevis I also parted with most of my comic book collection. I had accumulated close to 50+ short boxes over the past 25+ years. I gave away most of them to a friend, and kept only those few titles that really meant something to me. Usagi Yojimbo was at the top of the list, and is the only title I will never, ever part with.
I usually don't read a story until it is complete. One-shots I'll read right away, but stories that run several issues I will wait for them all to come out so I can read them all together.
Jabba, Usagi Yojimbo is one of the few titles you can read uninterrupted (they are without any annoying ads in between), and I recommend you pick up a copy one day.
