My Head Is Spinning

Currently, I am dipping into several fantasy worlds. All the writing is fine to good. The problem is the mental attempts to reconcile the world of George R. R. Martin's Ice and Fire saga with Fritz Leiber's tales of Fafhrd and the Grey Mouser and then jumping into Terry Pratchett's Discworld and then moving over to the shared-universe of Thieves' World.

Ouch.
