I mainly play on PC, and am mostly into older or less well known titles. I'm also addicted to download store sales, as evidenced by my mostly unplayed GOG.com and Steam collections. Those are completely tracked on this backlog, while my physical PC collection, also numbering at an estimated 1,000+ titles, is only updated as I actively go through my games.
Usually, I'm a completionist. However, I've also grown up and have a job, so I'm no longer wasting time on games I don't really enjoy. My tolerance level for frustration has sunk considerably, so a game that starts to feel repetitive can stuff it.
Related to this, my definition of the Completed status does not include the requirement of beating the game on hardest difficulty. Difficulty can often be arbitrarily high, and as good as never makes me enjoy a game more. Unless lower difficulties make certain portions of the game inaccessible, I consider a game to be completed if completely explored at normal difficulty.
I'm also somewhat of an amateur videogame history and research buff, so I also document, catalogue and archive the games I play. The main effect this has is that it takes even longer for me to actually go through a game. You'll find some of the data I collect this way on collaborative database projects like MobyGames or UVL.
