Just finished watching Juice it or lose it.
Juice it explores the little aesthetics and visuals of games and how they can be so much better with the smallest changes. Once they start to build up they can make a game look a lot more appealing. This also brings up something interesting that the core gameplay for a game does not necessarily mean
it will be successful. All areas of what make a game a game must be layed out and brainstormed thoroughly. A game is made up of all the elements, visuals and aesthetics, sound, gameplay, story (if applicable). But the main point of Juice it or lose it or what they were trying to share was that once you have your core gameplay
down work on refining the aesthetics of the game and how it can be more visually interesting.
