Just like the difference between movie theatres vs home theatres, arcades can be a very different and more (or less) social experience than playing games at home, but the appeal might depend more on what your home is like than what the arcade is like. You might live in a small space where you can't keep a functioning Dance Dance Revolution setup without noise complaints from downstairs, but you can dance at the arcade, maybe with an awestruck audience if you're really good at it. You can take your SO to the arcade on a date and giggle as you race down a mountain together with a steering wheel and pedal setup, even if he/she isn't into that kind of thing most of the time and wouldn't have fun playing Gran Turismo with you at home. You can hang out with your friends each week and play with them even if your home environment is too strict, chaotic, or unpredictable for that. But if you have everything you need at home and can couch-co-op Halo with your buddies on a big screen TV, you might not see any appeal in the arcade.
