Increasing Challenge in Roguelikes

There is a good article on increasing challenge in roguelikes over at the Temple of the Roguelike. As I've mentioned previously, I've probably gone too far in making Unangband hard and I now need to recruit people in order to play test the deeper levels, as Matthias Rudolf correctly points out. Its probably worth noting that the author, Andrew Grech, aka Roguery, doesn't discuss the difficulty curve of the original Rogue, which errs on the side of making monsters increase in difficulty faster than the player increases in power, as John Harris of @ Play notes.

It looks like the Temple of the Roguelike has got a few more people posting to it as well, as the recent flurry of articles suggests.
