This backloggery acts as a more or less comprehensive list of the games I've played. My focus is on beating games rather than completing them; outside of a few games I enjoy replaying for achievements, life is too short.
Liveblogs of many of the games I've played are available on my tumblr [Link]
and dreamwidth [Link]
and some recent games have brief spoiler-free reviews in the comments.
I don't add games to my backloggery until I've started playing them, but since I have a bad habit of getting a few hours into a game and setting it down I can never seem to get my backlog down to zero. My to-play list is over on my listography [Link]
which has some overlap here. See also HLTB [Link]
I only add mobile games if they're story-based or if I've spent an exceptional amount of time with them. Even then it's very incomplete, and not a priority.
