I did the same, except I finished Skin Game, then went back to the beginning and reread the series and short stories in order, mostly because I didn't want it to be over (and it was time for my annual reread anyway).
This year, I listened to the audiobooks for the first time instead, and recently finished them (I now understand everyone's praise for James Marsters's performance). An old friend convinced me to really read some manga for the first time a couple of months ago, and I decided to start with Berserk, so I didn't really have time (if you don't know, there are about 8,400 published comic pages over the last thirtyish years, so it was a lot to get through) to read the books even though I was due. Evidently, all of the manga I'm even remotely interested in is almost hilariously lengthy (JoJo's Bizarre Adventure, which I haven't looked at for twentysomething years, is somewhere around 24,000 pages; that may not sound like much, but holy crap is there a lot of detail in each panel), so I'm hoping I get to a good stopping point during whatever I'm reading to do a legit reread in the leadup to Peace Talks.
