i don't know where you live but if you don't have spare rooms, like a study, for your hobby & another room for your wife's hobbies then you are in trouble.
If space is a premium, I suggest you keep all your videos(vhs, dvd,...)
Sell most of your game consoles & get an xbox. Nostalgia is nice but if you aren't playing with your old consoles, sell it & get cash to get other things to add to your hobbies. At least other people(when you sell it) can enjoy & appreciate your classic consoles.
Just my opinion.
