This week in the class we talk about two topics. The first one is system dynamics. The second one is the information systems of games. In class, we look through games on the slides, and we try to identify what elements is in that game to guide us through to discover the space and environment of the game. For example in league of legend there is a mini-map on the left-hand side bottom corner for us to see where are we at right now in the game. Also in class, this week 3 of our classmates stream the Fornite game and play in front of the class. It is interesting to talk about Fornite this game, the space of the game will keep getting smaller and smaller as the game progress through time. And one other interesting thing we find is it may seem like it is a survival third-person shooting game at the beginning. But this game also has the other aspect when playing this game. Which is you can collect material and later on use them to build up building for hiding or attacking.  The system dynamic in Fornite plays a huge role. Without keeping shrinking the battlefield and if the player can not collect things and build up things from those resources. This game will just be a normal third-person shooting game. It is very interesting to see that if you change one aspect of a game as a game designer. The play style of a particular a game and the feeling message the game tries to tell the player will be totally different messages. Fornite this game gives the player a feeling like you are really on a battlefield, and you are forced to act, can not just keep hiding in one spot, because the map will shrink throughout the time. In the future, as we design games, we need to think about the system dynamics of a game, because you will never know what kind of interesting game will be designed when you just changing one aspect. For the information system of the game, it is important that can give the player some kind of ideas about what is going on in the game. For example when my classmates are playing Fortnite before the map starts shrinking there will be a timer running down and you will see a circle in the minimap. Without this kind of things the newer player of the game will get lost and confused, need a longer period of time to figure out how the game works.
