The crazy thing about Xbox games, or any game today, is that they require infrastructure, they require maintenance and subscriptions, and they require a constant release cycle, and moreover, a thriving community of humans who are playing the same exact game at the same exact real time as others. It seems like the primary lost art of gaming is single-player, offline, solitary modes.
Anyone could literally pick up an Atari 2600 from 1977, plug in a cartridge from 1978, plug it into a TV from 1981, and play the same exact video games with no problems. Now who will be playing the same Xbox games in the year 2076?
