"Like, instead of going and making a new game"

On Steam alone there is released about 1000 games per month.

New games are made all the time in all kinds of genres.

There is no lack of new or original stuff if that's all you want to play you can easily do that.

Remaking or remastering a classic is great becasue as time goes on it get's harder and harder to play and take of the old games. Games is unique in that it's so hard to go back to old systems to enjoy the old stuff, archiving is difficult.

So remasters and remakes are pretty important in taking care of and enjoy the good stuff that would otherwise be forgotten.

The idea that you think they are "sleazy" and "slimy" means you have fully bought into the dumb gamer outrage culture without actually putting a single original thought into it. You dont even know what you are mad about.

People putting in work and releasing a product that nobody forces you to buy is not sleazy.
