Ok, member and game tables updated to May 31.  Quite a bit simpler than previous, as my goal was to get the basic list completed.  Please let me know if you see any errors!  I'll re-add 2018 and most recent month additions with the June update.  Also planning to add a table for makers in a form such as this, hopefully with a count of total games, and average per game added in the final form:

Also, May releases.  Depressed since the thread had been dead for a couple months: 

I'm unsure about the "member rewards" stuff.  TBQH, I didn't pay close attention to what VersusEvil was doing with it, and I am not sure how much interest I have in maintaining anything that gets too complicated.  Open to suggestions though

I picked up a ton of new games recently, will have to add them to here tomorrow or so, great to see this place back up and running, I got a few ideas from seeing members here buying stuff.

Also for those with Rocket League the comp season just ended a few days ago and if you go in now you'll get an update with some new stages, a new vehicle and your season rewards depending on where you placed, pretty awesome that the season rewards this time around include a goal explosion, was pretty chuffed to get the Bronze/Silver and Gold rewards :)

Dope it lives. I bought battle chasers nightwar, street fighter 30th anniversary collection, mega man legacy collection 1&2 and the banner saga

Yeah, attach rate is new. Was an easy bonus since it's count / members.

As far as Xenoblade and Pokken go, I'd say those are first party. I'm largely basing on how Nintendo itself, coupled with independent publications, view the games. Though Pokken gave me pause, as Nintendo considers it to be first party in North America and Europe, but third party in Japan. I felt that was splitting hairs a little too finely, however. Also, ultimately, neither Monolith Soft nor Game Freak really exist outside of Nintendo. Same reason why I listed FEW and HW under Koei Tecmo - Team Ninja is pretty much just a part of Koei.

But Namco Bandai developed Pokken, so how is that different from Fire Emblem Warriors?

That's fair. Give it the same treatment - on the table, but unranked?

Third-party games I own so far:

-Doom
-Pacman Championship Edition II Plus
-Sonic Mania
-Wonder Boy: Dragon's Trap
-Bloodstained: Curse of the moon
-Double Dragon 4
-Celeste
-Thumper
-Ikaruga
-King of Fighters 98
-Metal Slug 3
-Blazing Star
-Magical Drop 3
