While its no doubt the company's primary directive to make money, such remakes introduce the younger generations to classic games they would have likely never played otherwise.
You bought the game and you enjoyed certain aspects of it, so for that alone I wouldn't perceive it as "drain". The way you worded that makes it sound like people would be forced to buy the game, which they are not. I don't see anything inherently wrong in making a product that banks on nostalgia to sell, as long as there is no false advertisement and as long as people are buying it out of their own volition. Besides, if you played the original back in 2000, you are likely in a place financially where you can allow yourself to shell out some cash for the occasional video game.
(if not, then you should obviously not spend money on games)
