Hello,


There is no government college as such that offers diploma in game designing course.However there are some private institutes like Arena animation that can offer you the course.But going for this course after 10th is a very bad option because you have absolutely no base or knowledge regarding designing and programming and that will later creat lot of problems for you in understanding this deeply.
If you want to become a successful and legitimate gane designer then you must go for B.E or B.tech in Computer Science after 12th.Or if not then at least first complete your 10+2 with science stream and keep computer science or IP as a subject and then after completing HSC you can go for Animation and designing course and side by side you can lear programming and designing.

I hope this helps.
