Jokes aside I really like Monster Hunter: Freedom Unite. It reminds me of playing when I would wrap up in a bed and play all day.
A while back I played Persona 5. For me that's probably the best made game I've ever seen. Everything about the atmosphere, sound design, environments and art direction is just right.
When I found myself with nothing to do for the last part of a day I just walked around shibuya. Night rain playing in the background as my character ambled down the street passing the crowds beneath an umbrella. It sounds dumb but I felt so content.
I should really get back to playing that, I've not touched it for so long. I think I'll try to get back into it when the next holiday hits.I think Katawa Shoujo is probably the game that has got the most comfy to me but that's 100% due to my circumstances while playing it
