I think everyone who consumes a lot of entertainment must run across this every once in awhile. It happens all the time with video games to alot of us too, and is a popular question topic on the Bombcast, but at least for me if I rack my brain those will usually come to me. Luckily, I'm mostly a console gamer and that helps narrow the field.
Books on the other hand are rougher. I had a really shaky plot-line in my head from a Science Fiction novel I read years ago. No character names stuck, or important objects. All I had to work with was this:
Future cyber warfare, everyone is immortal and fights for fun and something to do with their time. All while other mortal people suffer. And it was just a dude with a gun on the cover.
I'm fairly certain I read it in Junior High and I am a Junior in college currently. Over a month of trying to think up more of the plot and it wouldn't come to me. I kind of gave up on it, until I remembered I borrowed it from the Public Library. And long story short after bringing up a list of 1000 sci fi books in the library, I found the novel at #208.
So share your stories of this horrible affliction. Have any tips for others when this kind of mental block happens? Have any books or movies still annoying you with their fleeting memory? Post here, I'm curious to hear them, and maybe a fellow duder can even help! And don't be the guy who says "google it". That's great only if you know the title or director/author/actor.
P.S. The book I couldn't think of was War Surf by M.M. Buckner. My 13 year old self loved it, but can't say how it is today. I think I might just buy it so I won't ever forget it again. I almost jumped for joy when I saw the cover after years.
