Do you know any story without characters? No! That’s because, after the story, the characters are a fundamental part of any  game. You have to decide the looks and personalities of the characters, how fast they should move, what should be manners and characteristics etc.

That means it should support the game and yet not be too obvious! You have to decide the various sounds in the game world like player sounds, background music, etc. that together create a lifelike and believable video game.

It can be said that video games are basically just responsive art!!! So art is very important as it decides the feel of the game. Normally art in video games can include various things like the game texture, game lighting, 3D modeling of characters and objects, particle systems to create fire, fog, snow, etc.

All the lighting in video games is obviously artificial and very important for mood setting. Less lighting can be used in association with horror or thriller games while increased lighting can denote more adventure or fun games. Also, lighting can be an important factor in stealth challenges with darker areas providing cover to characters.

All good video games have various levels that increase the difficulty as time goes on. Levels can be denoted in games by multiple floors, different buildings, or even different countries (Depending on the game you are playing!) and each level can have many potential paths that eventually lead to the next level. And designing games with many possible path combinations for different levels is a big factor in Game Development.
