Ya, at the moment I'm waiting for the next books in 5 series that are coming out around that time :P
This list was published in Inquest #35, which means it was published in early 1998. Ilion and Olympos hadn't been published yet. Also, as far as I'm aware, the only novel that Pressfield had published at that point was The Legend of Bagger Vance.
And Beff, Snow Crash made the list at 96.
For a list encompassing basically all speculative fiction that was compiled by a bunch of guys just sitting around arguing in favor of their favorite books, it's not bad, but it's not perfect.
Sorry for digging up an old thread.
