And if they don't feel like that "effort" is worth the price of a full game, they can complain and vote with their wallet.
That's a problem cause gamers are indeed spoiled brats. Double dipping a game one year later seriously.. lol.. that's kinda luxurious to begin with..
The logic for a remake like that is to aim at new people, and no real reason to lower the price of the game as a new game.. It's not a 5-6 years old game.
Boards like neogaf create a distorted vision cause everyone buy so many games, and even some many times.. It's not the real world.
