Okay, here's some things on your examples. For the FF XIII port, the unofficial mod to include higher resolutions is actually already on questionable legal grounds. Depends really on how the mod writers went about things, but on a very very technical level they're probably breaking the law. Squenix /could/ go after them, they just haven't so far and probably won't. As it stands now, there's no case for financial damages to be awarded, and even if Squenix released a paid upgrade tomorrow, courts won't backdate that kind of thing. All Squenix could really get from a court is an injunction to stop distribution of the mod. However, all of this legal stuff is on the people who wrote the mod. The end user is pretty protected on this one, downloading and installing the mod may break the EULA, but that's a civil issue, not a legal one. Worst that can happen to you is that your game can get broken.WeepingAngels said:You fail to see how the same result can be achieved without buying the official DLC?
Let me give another example. Final Fantasy XIII was a bad PC port so someone wrote a mod to allow for higher resolutions. Now say that Square Enix decided to release paid DLC that included higher resolutions. Would that unofficial free mod now be considered piracy?
Don't like this example, there are a million more just like the Horse Armor Oblivion example. Why pay Bethesda for horse armor when there is a free mod that does the same thing?
As far as the Horse Armor Oblivion example, Bethesda gave the modding tools and permission to use them to the community. If you design your own Horse Armor as a mod, you have not broken any rules whatsoever. The only way Bethesda could go after you is if they could prove that you /didn't/ design your own, but actually used theirs. Bethesda sells things like the horse armor based off the idea that their offerings are better (or at least different) than what the modding community delivers, and the promise that their stuff won't suddenly stop working in any future patches. (Which is a laugh, given Bethesda, their stuff is probably more likely to break than most mods, but that's another topic entirely) Still as long as you don't steal their work, you're good to go, even if your stuff fills a similar niche to the end user.
Using Cheat Engine to give yourself purchased premium content of any sort for free would, most likely, be seen as theft by a court if there was ever a large enough scale use of it to ever make it to a judge (Which is, admittedly, hard to imagine happening). The DMCA specifically prohibits decompiling software in order to circumvent a system that controls access to copyrighted content, and the law usually doesn't care about things like "But it was /really/ easy to do!" or "It's my computer so I can do what I want."
