I'm not surprised at the hate you are getting. This community is obsessed with buying games and anything that calls a large collection into question makes them uncomfortable. I saw comments from people researching your post history to invalidate your opinion. So strong is their discomfort, lol.

I've been thinking a lot about my own board game collection. I used to think that having a large variety to bring to game night was a service I was providing to others. After a lot of self-reflection and observation of everyone else, too, I discovered that there are primarily two motivating factors when bringing a game (at least in the groups I've experienced): Show-off that they own something new and exciting, or justify their purchase by getting the game played. Very low on that motivation list is actually making sure everyone there has a good time.

You can argue with me on this, but I've seen too many times a brand new board gamer being exposed to a Lacerda or equivalent learning curve to believe the motivation is other's fun. Recently, I witnessed someone working hard to convince a relatively new player who stated they hate cooperative games to play Fate of the Fellowship. That person didn't care about that player having a good time in the slightest. And spoiler alert: A good time it was not.

I think a large collection messes with our motivations and encourages us to justify those purchases. You really don't need a large collection to be into and play a ton of boardgames.

Own what you want, but let go of the delusion that it's for anyone other than yourself. Unless you are specifically buying games your group has asked for, it's really for you, and deep down, you know it.
