Game design

To be a game designer, one must have knowledge of drawing and he must have a thinking process, which is unnatural. To learn how to develop games, one must be well versed with game development along with game design. Game design is not about multimedia software like 3D software or 2D software, it is a skill-set.
This field is divided into four parts:
1. Game development (Requires logic and art).
2. Game design (Requires art and skill-set of visualization).
3. Game art (Need excellent visualization and drawing skill set as well as color concepts).
4. Game testing (Need logic and efforts).
To make a career in gaming Industry, one has to have:

2. Strong interpersonal and written communication ability.
3. Organization teamwork.

There are lot of scope over here like gaming is now used at banks for marketing, for education, to improve the IQ, etc. One can start his or her career as a gaming artist, game developer, game taster, game de-coder, porting, etc. Another type of gaming is coming with lot of scope, X-Box, Nintendo and simulation games.

Hello Lahfir and Het,
CSE stands for Computer Science Engineering. It's a branch of engineering. To be able to get through to the gaming industry, you need to be good with coordinate geometry and graphical / visual programming. Visual C+, OpenGL are some of the various graphics based programming languages. You could try joining s good computer coaching institute to learn these languages if these weren't included in your engineering syllabus.
Once you've completed those courses, those institutes or you yourselves can apply for an internship in an IT company, regardless of whether it's a startup or MNC for a related domain. If you live up to their expectations, you might be able to earn yourselves a permanent job in the company and get started in the gaming industry.
Het, you can opt for B.Sc. (Computer Science or Information Technology) or B.Tech (Computer Science or Information Technology) or go for Bachelors with Computer Application (BCA) followed by Masters in Computer Application (MCA) to go for Gaming. Ensure you learn a couple of visual programming in your syllabus. If it's not included in your syllabus, go for a computer coaching institute to learn those. The remaining procedure is the same as I have already stated above.
