I've bought considerably less games over the past few years. Most of my backlog is from all the stuff I have on GOG and Steam and the innumerable sales and bundles I got from around 2012-2015-ish. Wasn't until early last decade that I really got into PC gaming, being a console boy my whole life. All the PC gaming classics I missed out on over the years combined with the flood of newer games from every corner has made it so that an unfortunate number of games remain unplayed.
I played so few games made the last decade I doubt I could put together a top 10. I'll get to fixing that, maybe, one day...
