How to design your videogame: design goals

Design a videogame is not a easy task. Even if you are involved in a big AAA title, or a simple 7DRL or a Ludum dare 48 hours challenge, you have to think about your design.

So today I want you suggest a small reading, here "Design Contradictory choices".

I like this kind of small blog posts, because in few word can help to see a problem on a different angle. From my point of view, you can see that many, many successful games have a lot of contradictory choices.
Take for example an RTS like Starcraft 2. As a player, you have to decide if you want to spend your resources build an army now, or expand into a new base, or create new building. These are all contradictory choices, constrained by the amount of resources player has and the time. Of course at the same time, player has to keep in mind what the other player/players are doing!
