I guess that’s debatable, depends on how you define what “it runs” means. PC gamers with dated hardware may be fine with playing on 1080p, while on the Xbox Microsoft might veto if it doesn’t run on 1440p and 30fps. Of course weaker hardware won’t run everything faster hardware can, you can’t just sprinkle infinite magic optimization dust on a game, there are simply limits what’s possible with weaker hardware, and once you’ve reached them you can’t just shout “enhance” like in CSI Miami.
