>5000 hours of counterstrike is pretty common game-time that students living there spend and you would easily find >25000 kids of age 15-16 such types. Millions of students go there each year. Competition is so tough that hardly top 2% get admissions into IITs.
As a result, >90% do not study.
You see them playing they are experts! Most of them don't even know how to log into a server. The cybercafe would set up the LAN for them. All they do is play, all the time. As per rule the shops are supposed to close after 11 pm. But these shops have eating/smoking and toilet arrangements inside. They pull down the shutter, as if the shop is closed from 11 to 6. Students stay 'voluntarily trapped' inside for a LAN party at a discounted rate of 1-2$ for the whole night. Once the course is over, the gig is too. they go back to their hometowns, never playing again.
I work in Delhi and I see clans participating and even winning international competitions like WCG. But even the gameplay of the best, is only at par average as per Kota standards.
All this time spent for happiness, curing boredom. Rajasthan would be the biggest consumer of CS, DoTA, Tekken, AoE if pirated stuff is counted for.
