Well, I wouldn't quite say that--though it kind of depends on which computer you mean and what time period. I still went to the arcade after getting my VIC-20, my Coleco Adam, and my Atari 800XL; and so did my friends. At those times, contemporaneous games at arcades still offered technology that home consoles and computers just couldn't match--so you were still getting a novel experience for your quarter, from higher res graphics, to color vector graphics, laser disc games, optimized controllers, etc. Basically, arcades still offered many of the the "gold standard" games, and like movie theaters were the place where you would experience great games first and at their best. The thing that stopped me from going to arcades was when that generally stopped being true. The two home systems that did that were the Nintendo NES in the console world and PC in the computer world (especially after EGA/VGA graphics and soundcard-based sound went mainstream). By this time, the typical arcade game was no longer even trying to be generationally ahead of their home counterparts (and getting increasingly behind); and conversion kits in battered cabinets, continue-play, and arcade machines that thought "bringing the home experience to the arcade" was a good thing, were fast replacing cool tech as the bait for your quarter. Arcades hung on for a while, but were no longer populated by tech nerds who were there to get their geek fix and career inspirations, but by those who just liked midway experiences--which wasn't enough of a draw to sustain them at the local mall.
