I've been using a Nethack-like system so far with a "more" prompt. It's good because it makes the player read all the (possibly important) messages, but I try to display important things in a more visible manner anyway, like coloring the PC green if he's poisoned. With fast paced playing the "more" prompt gets really irritating, so I want to get rid of it.
I very much like the idea of a game narrator, so I don't want to take the route of tiny, little, disappearing messages in the corner that no one reads. I want the majority of the players to read them most of the time. Is there a game that has this well implemented that I can shamelessly copy from?
