I got rid of all my cabs a few years back, many big hitters such as Star Wars, defender, sinistar etc, and haven’t regretted it for a second, although I sold just before the market exploded so did regret I didn’t hang on for a few more months…
I got two rooms back in the house and removed loads of stress.
I am getting back into gaming again - aes+ on order, and playing old console games on my 2600, mame covers all my arcade needs.
You don’t need a house full of games any more to be able to play them, emulation covers everything, so if you ever feel the need to play a game you can, but you won’t be faced every day with piles of stuff just waiting to break.
I think when the love is gone it is gone, if you feel like getting rid of everything then just do it, but I would hold on to a few special pieces if possible, there are a few items I do wish I had held onto, which I will never be able to replace.
