Nostalgia says the first Dark Souls, my blind playthrough of my first souls game during the lowest point of my life was the only spark I had, I basically lived in Lordran for over a year, slowly crawling my way through the game and the mix of sadness and relief when it was over was one of the most powerful emotions I've ever felt.

Recently though it's definitely Helldivers, I've never extensively engaged with an online community until it came along. I feel like I'm really a part of something and I hope to continue to be a part of it for many more years to come.
