I figured this place could use a puzzle thread seeing that adventure games contain many puzzles. I'll get this started (I've got work now but will return in roughly 6 hours to resolve actions. I've also got some riddles to post too. :) )
I gave this puzzle to a group I've been DM'ing. The people on the forum might like this one.
You find yourself in a small room. The voice of a small child fills the room
"There is one way out
But you can't get the key
The treasue is for you but the real fun is for me"
