Like I said, it appeals to the GamerGeek in me. I got a chance to roll up treasure and such from my D&D DMG, and my next stage is figuring out appropriate monsters for various "quests". It's keeping me occupied, and giving me a reason to do the housework beyond "I suppose I ought to".
A few weeks ago, Himself managed to pick up some bookcases on the extremely cheap (ie free) from a government agency which was replacing them. We now have four double-width genuine faux jarrah bookcases, three of which are now occupying various walls in my bedroom, and are stuffed with my books. The fourth is scheduled to go into my study/den/office when I finally clear enough space to move it in there, and when it does, the last three boxes of books will be shoved onto it. At that point, I will have discovered that mystic point known as "enough shelf space", which will most likely prompt me to immediate action, such as getting some more books. Of such things is life made. In the meantime, before I can start making space for the bookshelf, I have to put together the storage cabinet I purchased months ago, so I can use that to store stuff which is currently occupying the space where the bookshelf is supposed to go.
I am organised, honest. It's just that it doesn't look like it to outsiders.
My office/den/study is the next room on the list to get tidied up (one room each week, fifteen minutes per day, and then on to the next). The new tidying week starts Saturday.
