This is how every gamers react to a reboot or remake version of their favorite old game.
Admit it, you've been there too.
Some example of this that I can think of the top of my head would be:
-TMNT Turtles in Time remake (although it appear it was really boring to compare the original version because the gameplay changed a lot)
-Ultra Street Fighter 2 and HD Remix, People complained and bitched that the controls are dumbed down and the new hd graphics were ugly.
-DMC Devil May Cry, how dare they change Dante hair color
-Duke Nukem Forever; took 14 years of hellish development and it wasn't an over the top masterpiece and people were piss
I remember when the HD console came out, we got a bunch of reboots and remake and people were pissed because they modernized the game.
Edit: I decided to add a video from ScrewAttack that highlight my point. Some of the games in their list are just bad sequel but as a street fighter player, I can never get over people complaining about patchs in fighting games... Always funny.
