phew. you asked q at correct time.
B.E, B.Tech, MCA are sound options. anything with physics, maths, computer science is good. there are BSc courses with specialization in game design but AVOID THESE.
After that there are 2 to 1 year courses for either game design or game development, can opt for a good college with known placements in the industry. EA/Gameloft/Indiagames are some companies you might recognize atm that hire here. there are loads of places that provide shoddy diplomas and teach you the tools.
if he is up for it, he can do part time course in a local institute for game design during the BE/BTech years itself.
