I know 2017 is already half over at this point and that I really should have created this topic at the start of the year..but whatever. I'm doing it now. Live with it.
http://backloggery.com/ is a free site where you can keep track of all your games and mark them off as beaten and/or completed when you finish them. Using this site has helped me realize that I have soooooo many unfinished games. Every so often I like to make a thread here where I attempt to get that number back under control. It usually fails, of course, because there's so many good games coming out and I just don't have the time like I used to, but it's always fun to try.
I figure this thread can serve for 2017 and maybe 2018 too (or just keep going til it gets too long).
I'll start posting the games I've beaten for 2017 in the next post.
