I was collecting to collect at one point, (spending over $1000 most months), and then I realized I was never gonna get a chance to play over half of what I collected in my life, (most being RPGs). I have since calmed WAY down, limited myself extremely, (going for getting 1 game a month unless there is some crazy good deal like the PSN .99 flash sale), and play pretty much everything. I got rid of I'd say about 90% of my collection since last year and now have around 20 or games in the cabinet. Of course I am not counting PS+ games, steam or PC in general.
Though I really enjoy collecting games, I got to where I saw no point in it at all when I was never going to play most of em even though I wanted to.
And hopefully no one that does collect takes offense because I love hearing and seeing folks collections.
