Trick is - to put it somewhere where the missus gets fedup with it. Give some lip back (not too much - we don't want a smack in the chops) about not wanting to move it 'cause you're playing it.
Keep it out for as long as you dare and hopefully - at some point - she'll come up with an idea for you.
That's what happened with me...pretty much. It was on the dining table and not getting me at it that often...but it wasn't a game I could pack away. We discussed it. I said I can't move it but I'd try to get back to it. Eventually we discussed options...garden shed/summer house, loft, spare room that won't be spare all the time. She came up with "Why don't you get rid of those shelves and put a work top in there that can stay there with your game on it"
"Good idea love" I said
