When I was young, arcades were basically like high-end PC's (of the day). I used to play them, but only because playing anything else at that graphical quality would cost an arm and a leg for a PC.
But now, I am never at arcades. I don't even know anyone who goes to em. They are just expensive, considering I could have my own game system in my house with similar, if not better, quality. Not only that, but online gaming is dominating the market right now. You just don't get as much from an arcade anymore.
Back then, the length of a game did not matter. Most arcade and console games took only hours to complete, or at the very least, several days. Now, if a game is under 10 hours, people complain. This generation of gaming is just spoiled; I don't see any of them going to an arcade for anything but previewing a future console game.
