I will tell you what.
"GAMER ENTITLEMENT" is a behavior that is a reaction to another behavior,one of publishers and developers.
Let's see how it happens.
The root of the problem is a mentality a lot of publishers and developers have that the NAME of a video game is able to sell a game alone.It has become a common tactic and mentality across DEVS,and PUBS that whenever they are to make a new game,whatever that game might be,they will pick up the title of ANOTHER game,just for the sake of MAKING PEOPLE BELIEVE THE NEW GAME WILL HAVE SOME RELATION TO AN OLD ONE,WHILE IT'S NOT NECESSARY THE CASE.
It's quite simple: They make their own game,the game they want to sell,but because they are not sure it's going to sell they pick up the name of an already existing series with the hope that some nostalgic fools will hand over their money to buy a game that plays completely differently and has barely or not at all any resemblance with what the TITLE they picked up is associated with.
It's happening everywhere.
PERFECT DARK ZERO played nothing like PERFECT DARK.
DUKE NUKEM FOREVER played nothing like DUKE NUKEM 3D
WOLFENSTEIN 2009 played nothing like RETURN TO CASTLE WOLFENSTEIN
DUNGEON KEEPER MOBILE plays nothing like DUNGEON KEEPER 1,2
PREY 2 looked nothing like PREY 1
And the list goes on...
I could keep writing of examples.
The thing is,when a game is BAD and the DEVS/PUBS know that,they will pick a name of a good series in hopes that they will get some sales from the nostalgic fans.
And that's when the so called "PLAYER ENTITLEMENT" comes in.
It's a natural reaction to being fooled and lied. It's what you get when someone realizes that all the values,standards,attributes,and characteristics associated with a beloved brand aren't there on something that supposedly is part of the brand. It feels like getting convinced to buy an iPhone only to discover that it's not an iPhone,but a Chinese imitation that functions nothing like the original,and breaks one or two days after you bought it by itself.
If in the near future more DEV/PUBs are going to keep to naming GREEN games "RED" to convince people who like red to buy them even though they are actually green,there is going to be a lot of "GAMER ENTITLEMENT" anger on the internets.
If though DEV/PUBs become more honest and either name their new games a new name,or whenever they pick a pre-existing brand they carry on the distinctive features and standards of this brand,that people came to associate with this brand,then there will be no "GAMER ENTITLEMENT RAGE".
Pretty simple.
