For the purposes of a discussion about older games not being playable on modern OSes? Yeah, maybe. In fact it could have no code changes whatsoever, but just be recompiled against newer tooling to accomplish that goal.

But I'm talking about games that are getting extensive updates through their lifecycle. It's quite possible that some of these "same" games will be playable in 50 years via slow process of incremental updates. There's no reason to suspect those are any less supporting of modern hardware & OSs than newly released games.

There's already been some unconfirmed talk of GTAV being the last ever GTA, with a hypothetical major update just being a new paid-for area that'll appear in-game one day, as opposed to being a new shrink-wrapped game under a different title like you'd get in the 90s.
