Hello Stranger!
When I started collecting I kind of bought anything I could find, but now I usually buy only what I am interested in. Really though my collection specializes in buying to many games that I don't have time to play
Indeed, haven't seen you much on Twitter lately!
But yeah, too much backlog, but after a bit of excess with PS3 games, I reoriented my approach a little to try and focus in a bit more. I noticed that even with good handheld games, I just don't dig playing on handhelds all that much, so decided to scale back a ton there. Started cutting out series that I was just kinda so-so on like Disgaea, and will probably sell a few things. Fewer big collector's editions, since most of the stuff just sits in the box forever. So on and so forth. It's gone pretty well overall, though you can't prevent those occasionally disappointing games.
It's surprising what sticks, though. Pillars of Eternity and Metal Gear Solid V? Eh, they're OK, but not grabbing me like I'd hoped. Rise of the Tomb Raider and The Division? Fantastic!
