Belgariad first, which failed to impress very much, but also didn't disappoint as much as when I reread Elenium/Tamuli a few years back - it doesn't have quite the same offensive ultra-violent approach to problem-solving, despite one highly problematic passage glorifying marital rape. One of the interesting aspects of rereading that is just how much fantasy has changed in those thirty-something years, both in terms of complexity and in terms of socio-political content.
Now started on the first book of Otherland, which so far is just as brilliant, visionary and of course slow as I remembered it.
If this keeps up I may even end up rereading WoT...
