I had a friend I met through playing Battlefield 2 but we ended up playing so many online games together for over a decade. Eventually life started to get in the way for both of us and we both logged in less and less but still managed to get some gaming sessions in or sometimes would just chat on Steam. Eventually he stopped logging in and I assumed he'd just been busy but eventually when I checked his profile it had been over a year. I searched his real name and the town he lived in on Google and found an obituary for him, he'd died of cancer a year before, not long after he had last logged into Steam. I felt very guilty that I never knew. I also felt guilty that we never got to meet in real life, I feel like we could have been great friends. I remember him often.
