Nice! I actually did something similar to you late last year but forgot which bundle I stopped at. My wife is right in that I like to find ways to make things much harder for myself
I'm being selective which games I'm downloading that aren't on Steam as well as what I'm registering. There are a lot of mediocre (and bad) games in some of these bundles so I'm trying to save space on my external drive (for non-Steam) and keep my Steam library a little more curated. I will admit that I really want to pump up my library numbers in Steam but even I have my limits (Chicken Shoot will never be registered to Steam! ).
For what it's worth I'm recording what I do in a new spreadsheet, so maybe that's slowing things down. That and checking out reviews and videos in Steam. It's actually kind of therapeutic.
Code for Delve Deeper + DLC:
7VHPQ-TACI4-K3X26 TAKEN! Enjoy!
Let me know if you nabbed it so I can mark it off.
