Player incentive and motivation concerns are a huge part of game design. An action in a game can be highly advantageous, but if it doesn’t look advantageous to the players, they won’t try it and will never learn its true value. As a designer, you have to manage the appearance of contingencies as much as the reality of them.

Why you should try to streamline your game:

“Before you say that your game will lose something if you try to streamline it, be reasonably sure that there isn’t a way that will make it easier on your future players and virtually the same when it comes to the feel of the game and the number of options it provides.”

As a game improves, the fraction of potential modifications which will improve it plummets. It gets to be like looking for water in the Sahara. One characteristic of great game designers, which I try to emulate, is they keep looking longer than everyone else.
