Today I learnt about visual style and gameplay. We discussed many points within either categories and also used this link to help. An interesting aspect I found was the fact that the level of detail must be relatively equal between the main character, NPCs and enemies.
Another good point was getting the balance when considering addiction. A good thing to incorporate into my game would be rewards that are given just regularly enough to keep the player hooked.
Attached are my notes from the lesson outlining what was covered.
