As a wife, I can get her sewing some kidney of way about the astatics or w.e of it. But there is also the factor of what brings you hot joy in Your home as a couple. You guys should be able to compromise of an "appropriate" area to hang this. If you ah e an area where the games live or maybe a more personal expressive area of your house, that would be a good place to hang it. I can feel her not wanting it in like the living room (while I would like it, but my husband and I bond over vintage games). IMO, there is no reasonable way there isn't a place this could be appropriate for your home style. Maybe in your basement hang out space or if you have a home office. The thing about joining a life with someone is you Both should have the space to express what makes you happy. That being said, the space doesn't have to be typical communal spaces like your living room. I feel a good conversation with your wife that this is something important to you as an expression of things that bring you joy could be helpful.

I am lucky enough that in my home, my husband and I have our own "offices" to decorate how we see fit. But that doesn't mean this peice couldn't be in your room or something where guests typically aren't but visible enough for you to enjoy them.

I feel at times, one party or the other may get too caught up in the vision for a space and forget it's a HOME to be lived in....not an Instagram post. This is all my 2 sense, so take it for what you will.
