So I have a lot of overlap. To be fair, a bunch of that overlap is due to these gentlemen.

I will have to do this overlap thing as well. I think Iāll use a diff tool 
When I get to my computer.
We need an Ava video next.
And then we need to figure out the most-owned games and do we actually like and play them?
What I buy: cheap, small boxes that are easy to justify and fit on the shelf
What I play: 45 minutes or less with low rules overhead, based on the tolerance of the others in my household. Or strong solos.
What I like: Generally 3-3.5 BGG complexity games, euro/conflict hybrids that require about 5 games to fully grok.
So yeah, weāll give Pipeline a chance. Even if it takes some time to give it that chance 
This is more consistent than I expected:
Overlap with Tom: 19/101 (19%)
Overlap with Matt: 14/60 (23%)
Overlap with Quinns: 33/138 (24%)
Iām especially surprised that I have a similar overlap with Matt to the other two, as Iām not often excited about the things he seems excited about.
What i have in common with all three of them
Looking at the lists, my overlaps are currently as follows:
Quinns (as of April 2019)
Matt (as of January 2020)
Tom (as of March 2022)
I had this pending, and last night I was a bit bored, so here we go:
Overlap with Tom:
-Decrypto

Overlap with Matt:
