but i don't agree that people who are torrenting games wouldnt buy them if it was possible to torrent.
I know quite a lot of people who says they would probably of bought many of the games they torrented if they had no other way to get it for free.
You may not agree, but most experts say otherwise. Your evidence is anecdotal at best, and it certainly seems to not consider the bigger picture. I wish I had the source, but I read statistics on android piracy that showed that something like a 2/3rds of pirates don't play the game longer than a few minutes -- about half of them didn't even play it at all. This means that, of all pirates, only about 1/3rd are giving your game a second look. Many of those pirate because they are too poor or cheap to pay for a legit copy at any price, and still some more outright object to the notion of paying money for any software at all. In the end, you have perhaps 5 or 10 percent of pirates who are even on the fence over paying you. Who you still have to convince that your game is worth your price... Hence, you cannot think in terms of "X people pirate my game, my game sells for Y, therefore pirates have cost me X * Y dollars." Even with perfect (read: impossible) piracy prevention and perfect (100%) conversion to paying customers, its more like (X/20) * Y -- best-case-scenario. DRM and anti-piracy task-forces are not the crushing theft/would-be-windfall that the MPAA, RIAA and other industry groups would have you believe.
Seriously, the best thing an indie can spend his time on is making his game better. DRM and anti-piracy measures do him exactly no good, and will do harm to his reputation.
