Most 32-bit games won't be updated, we'll have to resort to faking the time to play many of them.

Most 32-bit games written for some form of Unix will use the system time_t if they care about time. The ones written properly, anyway. Modern Unix systems have a 64-bit time_t, even on 32-bit hardware and OS. If it’s on some other OS and uses the Unix epoch on a signed 32-bit integer that’s another design flaw.
