Sorry but I laughed at the suggestion to go out and look at the sun haha.. but I definitely agree on the idea of prioritizing the real world as much as possible. I think looking back I'd be glad I didn't rush to play all the games I could, but at the same time it's all up to what you want to do OP and I understand you have a lot of down time in the winter. Also I'm not sure of how much you're into movies OP, but I think that's another great way to absorb a lot of beauty in the world with shorter stories (I'd ask the same question on the Movies subreddit if so).. whereas the people saying to play the Mass Effect trilogy etc (I enjoyed it too FYI) makes me think it'd be a bit of a waste hours-wise with your limited time, but that's only my opinion.
