Hello Praveen!

Behind the making of a Game there goes lots of things. 

Programming skills, 3d modelling, Animation, VFX skills, etc.

Being a computer engineer you would be having knowledge of Programming.

At least you can use your Programming skills to be a part of the making of a game.

Hope that helps!

Dear Praveen, you have an interest in designing a game you have to understand which skills are required for it like you have to learn fundamentals of designing  and you also have well knowledge about Playstations, Nintendo Wii, Microsoft Xbox and the most important part is computer programming;Do some online valuable online courses by XBOX which give you real experience of it.

There is a lot of benefit from it because it has a very high market in the international market and a very high salary.

All the best
