I am using tata sky service for the last 12 months. It is good, and after the recent add up of all the sun network channels, it has become nice, with a cluster of south indian channels. The service, I experienced is trouble free. Customer service people are also freindly, recharging is simple.
The main advantage about tata sky is freedome from the local cable guy, their regular excuses of power break down in their place, shuffling of channels without any prior information and at their will , etc. Games for the kids are good and I found those innovative too.
The games also they keep on changing and upgrading occassionally.
There are different tarriff plans also being introduced now, to suit the type of individual usage patterns. Being into a new service industry, I hope there is a big scope of growth in the field and a lot of service up gradations.
