I was going to comment harvest moon after reading the title!
A lot of the older games for me. They're just a lot harder. Like maybe they expect you to be willing to replay an area or a level over and over, getting a little farther each time until you beat it and I just don't have the stamina for that anymore, or the time.
Newer games baby you, they increase the difficultly perfectly along side your ability growth. They might even make a level easier if you've failed twice. Older games don't care if you're having fun as much. There was less competition (fewer game choices) and more of a "gamers like this. If you don't like it, you're not a gamer" attitude, and now games want to attract everyone.
I have become such a baby about games. I want to have fun the whole time! I can't handle failing over and over. I'd rather just read a book.
