All this talk about DL has reminded me of my least favorite Setting to play in. Krynn always seemed like a pointless waste of time to play in, because all of the interesting things one might do in any of the interesting places were/had been already done by characters from the books.
As far as the worst Game I ever played/DMed in, that's Shadowrun. Bought the books, got my friends together, we rolled up characters (even me, the ostensible DM), and roleplayed for about an hour before we got to our first fight...
...and not one of us could find a whiff of combat rules anywhere in the blasted book.
Worst.
System.
Ever.
