Okay, This is TOTALLY RidiculousKing's Bounty Gold (which includes both the original game and the Armored Princess expansion) is selling for $11.25 on Steam right now (thanks, Qt3 forums).
I just finished the expansion last weekend, and both the original and the expansion are superb games. I'm going to write a long post about both next week, but this is basically 80+ hours of outstanding gaming for $11. Insane.
Oh, and if you remember the crashing problem I was having with the 1.65 Atari retail version, once I started playing the 1.7 Steam version, I had zero crashes in 20+ more hours (I kept my save games, so I didn't have to start from scratch) with the original, and 40+ hours with the expansion.
