Game Design and Development

Starting from the point of view, Hacking doesn't requires eligibility of academics. Hacking is just a skill which requires, Coding Knowledge, Network Knowledge, Server side Scripting Knowledge, Computer Hardware Knowledge and Testing Knowledge. Coming to the part, if you saw the articles, the children are around 5-11 years of age are hacking networks, finding zero day flaws in software etc. So, this shows hacking doesn't require any academic courses. Learning hacking through any certification such as EC - Council CEH, (ISC) 2s CISSP, CISA and CISM from ISACA and OSCP from Offensive Security will improve the professional skills of hacking.

For Game designing:
It's good that you are starting, when you are young. The first thing is that you should know what game design is actually about. You can read the book "The Art of Game Design" by Jesse Shell. If you are really think that this what you want to do then read on. Otherwise check out other fields in gaming such as art and programming. Learn some basic coding, preferably in C+. Also get hold of a game development suite such as Game Maker, Unity or Cocos2D. I personally use Unity because of their great asset store and user community. Start making games on these platforms. They should be simple enough! Don't go off thinking that I have this great idea for a super game that will make millions and start off biting more off than you can chew. This kind of attitude would portray you as a quintessential amateur gamer. Also start paying close attention to the mechanics of every game you play, whether it be on mobile, tablet, PC or console. Question everything that you come across - how is the combat system designed, why are the rewards structured as such. Etc.

Relevant educational qualification in the fields of animation, graphic designing, game designing/ technology, etc. is necessary for obtaining an excellent career in gaming industry. Those interested in pursuing a career in gaming industry, should focus on gaining awareness with computer programming in an object-oriented language such as C+ or Java, from their high school level, so that they can build a bright future for themselves.
Several certificate and Diploma programmes in game designing are offered by various institutions. Advanced Diploma in Game Design; Diploma in Game Design and Gaming; Video Game Design and Development Certification; Video Game Design and Development, etc. are some among the courses. The minimum eligibility required for most of these courses is 10+2 or its equivalent. For becoming a Game programmer, one should have B.E/ B.Tech degree in computer engineering. Online programs are also available in game design and animation. Those with an inborn desire to learn gaming and excellent technical skills can excel in this field.
Good working knowledge of the game designing software's is a must for a career in game industry. Once you decide on the platform - I.e. 2D or 3D you want to pursue, you should get familiar with its applications - 2D designing software's such as or 3D applications like 3D Max/ Maya/ XSI, Light wave 3D, Cinema 4D etc. And computer graphics, data structures etc. They should also be exposed to art, literature, philosophy and history as it helps to create games with specific cultural touch to a particular region/country or people living in various parts of the world.
Personal Attributes - Strong interest and liking for the games is the first and foremost thing needed for an individual to become an expert professional in the gaming industry. Candidates who wish to make a career in game designing should be innovative, creative, systematic, dedicated and have a clear understanding of common game mechanics and game play theory. One should possess the art of sketching or drawing and have a sound understanding of anatomy of humans, animals or birds and body movements and lighting effects. Game designing is a field which requires a keen eye for detail, loads of patience, excellent communication and presentation skills. A game designer must have a good sense of colour, proportion, size, design, visualization, knowledge of background, art and layout.

People who pursue degrees in game design and development often have several of the following traits:
Detail-oriented
Goal-driven
Problem solving skills
Good communication skills
Troubleshooting ability
Works well in a team
Advanced math skills
Computer kills
High manual dexterity
Hand-eye coordination
Creative thinking
Writing skills
Drawing ability
Associate Degrees in Game Design
Most associate degree programs in game design and development take at least two years to complete. Some may take less time, depending on the nature of the school's curriculum. An associate degree in game design and development can prepare students for entry-level jobs in the game design industry, usually as entry-level programmers or other lower level positions.
Bachelor's Degrees in Game Design
Most Bachelor's degree programs in game design and development take at least four years to complete. Some may take less time, depending on the nature of the school's curriculum. A Bachelor's degree in game design and development can prepare students for entry-level jobs in the game design industry, usually as intermediate-level programmers, engineering staff, or beginning designers.
Those enrolled in either online or campus-based degree programs may also work on many group and individual projects, completing several games before graduation. This allows the student to follow the process of designing and developing a video game from start to finish several times through in a controlled environment.
Engrossing video game, be prepared to obsess similarly over completing a game's design. This often requires working overtime, staying late at the office, and coming in on weekends and holidays.
