I've always looked at remastered and collection bundles on new systems as a bonus to those who might not have owned a previous generation console(s), but to each their own I suppose. I personally chose to buy a PS3 this year to go back and play all the exclusives I missed, but in no way am I upset or am demanding compensation for PS3 titles I bought that are now moving to the PS4. That would be ludicrous... in no way, shape, or form was I promised a copy of any games I've bought for future generation hardware. That's like saying, for examples sake, that anyone who bought Final Fantasy titles for their NES/SNES are entitled to the PS1/PS2/DS/etc versions that came out since.
I understand that at the base of this argument it comes down to backwards compatibility, but that isn't something they HAVE to promise the consumer. I agree that it is frustrating, but developers are in no way scamming you/lying to you/cheating you when releasing updated or remastered versions. As a PC gamer I understand that I won't always be able to play my older games as hardware and software become un-supported. With my 3DS I am happy I can play my DS library, but don't fault Nintendo for not allowing 3DS games to be compatible with my DS (I would call this common sense).
I suppose the simple answer is to not buy them, but that seems to conflict with some peoples view on the matter. I am by no means a game developer, but I imagine some people picture someone in a dark room hitting CTRL+C and then CTRL+V.... and voila!!! Time to sel... I mean ripoff unsuspecting gamers! Last time I checked no one is holding a gun to mine or anyone elses head that bought TLOU on PS3 to buy TLOU on PS4. I bought the PS3 version knowing the PS4 wasn't backwards compatible at the time, but I'm not upset that they are making it for PS4. If gamers want to buy it again then good for them, and if someone who bought a PS4 wants to buy it because they didn't have a PS3... guest what? Good for them too!
I think some gamers don't realize that people buying these remasters, HD collections, and franchise collections are those who might not have owned a previous generation console or can't find the older version legally anymore (and don't want to pirate it). I don't think the developers are sitting in their offices rubbing their hands together thinking that everyone who previously owned the game will buy the new versions - regardless if there is new content or not.
I get it though... gamers feel cheated. When you bought your PS4/XB1 you were fully aware (or not if you didn't research) that it didn't have backwards compatibility. Sony, Microsoft, Nintendo, and all developers do not owe gamers anything if they decide to release a game on a new platform. I think it is a very entitled viewpoint to only look at yourself any deny new gamers or gamers who didn't own "x" console to play game "y" the opportunity to buy it on their new platform. It's sort of (more so the entitled attitude) like Steam sales when people piss and moan that nothing good is on sale, but to a new PC gamer it's heaven.
One gamers "rehash" is another gamers new and interesting experience.
