There are a lot of game devs who do this. GameDevTycoon for example lets you get bankrupt, because of piracy, which is the best thing i’ve ever seen.
The truth is, you should not worry about it at all. Ubisoft tried so many different ways to block piracy. The biggest fail was there DRM thing, where you needed
to stay online. They did not prevent any piracy, but lost a lot of customers who did not want to be online all the time.
You just need to accept that people who don’t want to buy the game, won’t buy it. So even if they pirate the game, you lose nothing. That person will not buy
your game, at least not at full price.
So i would not bother with that and just focus on making the game fun enough to be bought.
PS: Only games that need a constant connection to online Servers (MMORPGs for example) and these that don’t have Singleplayer in it, won’t be pirated.
Although even that is not true, because World of Warcraft for example has huge Private servers. They are buggy, but people are playing on them for free.
But here again, these people won’t buy the game and pay for it, so why losing a thought on them (:
