I'm not too old to play difficult games, I just lack the time, and often, the interest.
QTE-based combat where timing is everything? Sure, could learn it. Don't care to.
Blue Prince is difficult, but it's engaging and I love what it stands for and is about.
Mostly I play Animal Crossing just to relax after a long day. I love just hanging out on the island. But I also have another game I play, one with a narrative. So I'm finally doing Mass Effect with the legendary edition trilogy, got it for $6. All three games and their DLC. Couldn't say no to that.
