I haven't kept up with Jeremy Parish's personal writings, which is sad because he's my favorite writer in games journalism. I also have delusions of buying the book versions of his GameSpite stuff but it quickly becomes too much (I'm actually reading through the GameSpite Quarterly on the SNES right now). The Game Boy Kid Icarus, Of Myths and Monsters, is really good, by the way.
I'm playing through El Shaddai right now for Backloggers too. It's fun but very strange lol. After listening to the introductory BA podcast, I decided to take the advice of the special guest and play it on Easy and I'm glad I did. The combat feels about right. I imagine the bad guys probably have too much health on higher difficulties.
Snee pretty much summed it up about Foundation. The original Foundation trilogy is absolutely superb. I've never heard of Philip Jose Farmer though. I'll keep an eye out for his books.
