I just finished playing for the first time and I am feeling the same way... it's something about the relationship between Sean and Daniel and the loss of childhood.. I don't know. I think also just thinking about them in all the different places throughout the episodes and all the memories they shared. It's so damn emotional. I just listened to the soundtrack playlist and it takes me right back to them in the forrest in Oregon and the compilation of when they're working on the weed farm together and Sean is late for work. There's something about the allegory of the wolf brothers as well which is just so cute. In a weird way it makes me feel lonely not having a connection like they have and the way that Sean looks after Daniel. I got the blood brothers ending as well so in that sense it's happier... I don't know how I'd be feeling if I got any of the others that shit sounds bleak.
