If all resources are plentiful, this idea works marvels. But what if resources are not plentiful?
An example of scarcity
Imagine a game of Catan in which the sixes and eights are on forests, while meadows have only the 2, 12, 3s and 11s. There most likely will be a great surplus of wood, while sheep will be in very short supply.
Either I give you 10 Euro right now, or I’ll give you 10 Euro in a year. Which do you prefer?
Under normal circumstances you would prefer the money right now. Because maybe I’ll forget in a year or have gone completely bankrupt by then. And spending money now is way more fun than knowing that you can spend it later.
Thus, people generally have a preference for getting things sooner rather than later. With a technical term this is called the “time-value” of something (or even more technical, the “time-discount”).
Time in board-games
Time in board-games works somewhat differently than in real life: In a game of Chess it’s not uncommon to think for many minutes of real-time, in which nothing happens within the game. Then in a second you move your rook and the board has suddenly changed.
