A good point about sleep, unfortunately the BD&D party can only use Sleep once a day (1st level wizards only had one spell in BD&D). So sleep is awesome for one encounter, usually the first big encounter of the day. In play, I remember BD&D being an extremely bloody enterprise, with lots of character deaths, sometimes the same player losing multiple characters in an hour. D&D3.5 is rarely deadly to PCs by comparison.
Yes, because 3e characters are walking around in plate mail at 1st level?
Let's see, in my World's Largest Dungeon game, which just hit session 44 (each session is 3 hours) and average party level 9, I've had 11 permanent deaths and 7 short term deaths. But 3e isn't lethal enough? I beg to differ.
