This isn't a complete idea, just a general hey-this-would-be-cool.
Scenario: Server has some kind of theme, for example, steampunk. Let's say your goal is to get as many points as possible to your score, for the sake of simplicity.
In order to increase your score you need to build a series of machines that fire relays and make subtle sound effects (unless they overheat and explode or something) all based on Blueprints. In some way based on the type of server, you can get blueprints periodically, allowing you to see the bricks needed and in which places to build your machine.
Of course there's the flaw where a player would look at another player's machine, but you could simply only allow them to build that structure and make it functional if they have the blueprint.
Or maybe make it something completely different, I just thought the very general concept of blueprints would be a neat idea. Even if players could make their own and post on a little database.
