So, in other words, you would rather know how the book ends before you read it.If a DM tried to pull that kind of thing on me I'd walk away from the table and never play a game with him ever again...
Seriously, something like "the world will explode in 5 years" needs to be laid out on the table explicitly from the beginning, before the game even starts. Keeping the central premise of a campaign a secret from the players is a DMing sin. It's unforgivable and utterly despicable.
It's the same thing. I admit I used an extreme example, but the premise remains.
Can't speak for you, but as a player going into a campaign I don't want to know what ideas the DM has for what will happen 5 years down the road - I'll either find out through play or I won't; and if the world blows up because I and my party screwed up either through ignorance, bad luck, or bad intention then so be it. (I've actually been in a campaign just like this - as a party we knew we had to either do something or prevent something from being done but we weren't sure which, or what (we weren't that good at information gathering) - so we did what we could and thought we'd fixed things, but we hadn't; and next full moon the world blew up. End of a 10-year campaign. I still play under that same DM, and have for the 20-odd years since this happened.)
So letting the plot unfold (and morph, they always do) on its own, with the players learning about it as they go, isn't good enough?"I'll keep it a secret so I can ramp up the tension later, but it's not my fault if no one learns about it, so I'll just destroy whatever they do enjoy playing out if spite" is simply being a pathetic and petty human being. It breaks every rule of storytelling and the entire premise of the DM/player social contract.
Sorry, but in that example, the thing that needs to give is the DM's ego. Absolutely no question at all. Not even close to being ambiguous.
The DM absolutely needs to make the premise of a campaign clear to the players from the beginning. After all, he's asking them to dedicate a lot of time and energy to the campaign. Who cares if the DM invests "more" time if its built on deception and a disregard for the time and interests of the other players? This is why having the group sit down and talk about what they want to do with the campaign and what they want from it is absolutely essential before the DM even starts planning anything.
It's not ego, it's maintaining a mystery.
I'm not sure, but I rather suspect if I took a poll of the players and DMs in our crew they'd prefer not knowing the ending (assuming a "hard" ending is even planned) ahead of time either. But, I'll ask, and get back to you in a few days.
