Shadowstalker16: No official ban but the publisher held off on their own accord. I think the reason cited was that its because some bovine looking enemies in the game were called ''Brahmins''. No clue about if its the same with Fallout : NV though. Similarly EA held off on releasing Dragon Age : Inquisition, and I think reason was a romance-able (read fuckable since its Bioware) centaur looking guy called Iron Bull.
Siegor: I honestly don't know wether to laugh or cry... Such lame excuses.
Correct me if I'm wrong but I would guess India is quite a desirable market.
Probably not as desirable as many others, especially when fallout 3 came out, but now that steam supports our currency and our minimum download speeds are up, I'd say companies probably see it as a good emerging market. Piracy rate was and is high, but certain paid games have become very popular (namely CS : GO and FIFA). The potential is definitely there though. Certain sites that sell only (physical) gaming stuff have existed for quite a long time, so there is profit to be found.
EDIT : found this while googling for another thread :
http://steamspy.com/country/ India is ranked 37 on umber of steam users.
