Grey area for me, i find the reasoning to increase prices and/or give you ridiculous copy protection to defend against piracy ludicrous, piracy will always be there, always, so its best to cater you're games to invite people to enjoy them and pay for them. If a "customer" for lack of a better word has a good understanding with a developer then this will dissuade them to pirate the game, i would of gladly paid full price for any Bioware game 6 years ago for example, but now with the rampant DLC and destruction of my favourite franchises thats no longer the case, atleast not until i try them.
Which brings me onto my next point, i heard about the walking dead from a friend, having never tried any telltale games in the past, i new nothing about it. I downloaded the first episode from a certain site and immediately fell in love. Ofcourse i purchased the pass straight after episode 1. I believe piracy is okay in these situations, if you are like me and are fed up of being burned by greedy corporations and feel its necessary to try the game (i realize many people use this excuse and still dont pay for it). I would never have purchased TWG without pirating it as strange as that sounds.
TL;DR I will buy games if and only if i feel i am getting a just amount of bang for my buck as it were, and with companies i trust, Stardock, CD Projekt etc. I would probably add TTG to that to with the actual deliverance of promises with TWD, which is a noble thing in the games industry of late, keeping you're promises.
