Seventy-one (71) countries and dependencies competed in the 2010 Commonwealth Games
India is part of the Commonwealth; a number of countries under British rule. All countries in the Commonwealth are entitled to host the Commonwealth Games. If by "should", you mean that it is seen as a rather poor country, you are wrong. India is a fairly big business capital, because lots of trade happens there. It is on par with, say, Thailand or Malaysia.
There are dozens of countries that are apart of the commonwealth in 2012. Some of these countries are Malawi, Canada, India, Australia, Malaysia, Ghana, Dominica, and Samoa.
Two other Commonwealth Games nations are India and Kenya.

All but two members of the Commonwealth of Nations were former British territories. That's the link. By the way, Zimbabwe is no longer in the Commonwealth.
