Yeah... I didn't read the articles. Because I'm a hypocrite xD My point was still relevant though... Just for some perspective, on one torrent site, new game releases generally have 1000-2000 people leeching and old games have 100-200. This is pretty constant, so you can have some idea of the scale, and taking into account the average number of people each person shares the games with... also they could do anonymous surveys and stuff, which would allow them to create a confidence interval and, if they came to the conclusion of 95%, it would mean 95 +/- 5%...
I dislike required connections but they are the best way to prevent piracy. It worked for Diablo because the game was built around the concept but, for a collection of last-gen games, adding required internet connection isn't well justified.
some 1 time registration would be an idea though, maybe even registering required for each new PC the game gets played on so you cant just move the file to a new computer. I actually love steam for stuff like this, it fights DRM and is awesome! who needs to pirate games when you have steam sales.
and KH could be one or the other with how hyped people are, it may be a last gen game but its one that was on PS2 and never playable on current gen consoles. while that isnt enough you still have the fact that final mix content is thrown in there as well which might not be that big for japan but for here its awesome and a huge incentive to buy outside of reliving childhood memories. and if it was on PC mods would add onto hype as well. think of the possibilitys! kicking ansem SoD in the nuts!
