Design

The curriculum for Game Art and Design course is:
The first part introduces the foundations of design and game development. The evolution of games, different types of games, related terminology and technology, and the hardware using in gaming. Subjects like drawing and composition, introduction to games and classical animation may be taught. Students usually begin to maintain a portfolio for life drawing, environmental drawing, gesture drawing, still life studies, perspective and composition, and also use software to develop a series of digitally designed images. The second part covers the process of storytelling and visualizing. Students may be expected to brainstorm ideas on their own, fabricate a story around it, make the storyboard, and also design characters, backgrounds, props, levels and other aspects of a game. The third section of the course may cover subjects like modelling, texturing and lighting, rigging and animation, effects (FX) for games, and how to infuse sounds into the game.

There are two aspect of worth in terms of learning. Well BITS distance education is worth in terms of learning because it provides a vast syllabus.
Now coming in terms of value in the industry you will get a call from companies that consider BITS tag but from here come the twist.
Most big organizations won't consider this as degree and HR will reject as many of my friends have faced that and it won't be same as on campus because they will able to identify you have done distance education as a degree.
You can do Ph.D but it depends on the university as top university won't consider the distance education but from the learning point of view its good.
