not only games but many movies too come on dvd9. strange thing that got godfather(all 3 parts, in excellent quality) on dual layer for Rs 100 only! (and that too a yr ago!)that's why i had thought too that dual layer wud be under Rs 100, but sadly they r not!
Ya, Rang De Basanti was on Dual Layer DVD. Ripped it, and fit it into a CD . Also, I remember PC World used to give out dual layer DVDs with linux distros in them along with their magazine for just Rs. 60.
