@everyone - I think I've added everything, but let me know if I missed something!

No rush whatsoever, but there's a removed game Steam sync isn't picking up:
AppleSnake - Christmas Story https://steamdb.info/app/794870/
There doesn't seem to be much of anything on it anywhere, but since it was a freebie at one point, I'm guessing a few others might be missing it in sync.

Strayed (http://www.completionator.com/Game/Details/27030) is the old version of Brine (http://www.completionator.com/Game/Details/36805), as far as I'm aware, if you want to merge them/update what gets picked up/ignore me.

Gamecube stuff...

Bleach GC: Tasogare ni Mamieru Shinigami https://gamefaqs.gamespot.com/gamecube/929849-bleach-gc-tasogare-ni-mamieru-shinigami
Pure Evil 2-Pack https://gamefaqs.gamespot.com/gamecube/929724-pure-evil-2-pack

@Sylaris - That's weird about AppleSnake. I haven't seen it come across the Steam import, which happens a lot with DLC, but never with full games (which I assume this is). Unfortunately, there's not much I can do in regards to the import, but I did add the game to the database. Thanks for the heads-up on Strayed / Brine. I added an item to my task list to merge those two entries.

@psychoapeguy - Those have been added!
