I'm going through a period of stress and anxiety and I'm looking for some games to play on my 3ds that are good for chilling.
I don't necessarily want a "boring" game, something engaging is fine. I want it to be low stakes and not too difficult or stressful, but without being boring.
It depends for me. Something that fits your bill that I adore though is the Professor Layton games. Relaxing puzzles and a mystery to unfold in a world of the unknown. It's a very charming series!
For me lately though, it's been replaying the Zelda games. I just got to A Link to the Past and it's been a huge help when my stress gets bad. I hope things get better for you though! :)
Edit: I also recommend the Ace Attorney games, they gave me a lot of comfort in a very troubling time in my life.
My first one was the Ace Attorney crossover due to being interested in that at the time, but I've been playing through the Curious Village recently and find it very charming! I think either of those would work.
