I was looking through the thread entitled "If there was one thing about 3rdE that you could change, what would it be?" On the fourth page of that thread the moderator Dinkeldog summed up the thread rather nicely:
"Notice that almost all of the recommendations here move 4E even further away from 1E than 3E is. There are calls for to-hit locations, eliminating classes, reducing classes, removing hit points, changing magic systems, and eliminating alignment."
While not identical to my list of four things, it is certainly similar. I wish I had thought to mention d20 Call of Cthulhu's lack of a "fire and forget" magic system. I've seen several people (including some in the above-mentioned thread) complain about D&D's Vancian magic system. In CoC you can cast any spell you know as many times as you wish. However, you don't want to cast spells too often because doing so hurts you (usually by reducing ability scores and/or sanity score).
