Wait… Y’all are talking about X-Wing: Rogue Squadron and Star Wars Episode 1: Battle for Naboo, right?
I owned those windows ports!
They worked great back in the day - I had such a blast with them that I begged my parents to get me a shitty Logitech joystick! If you want to check them out, it looks like Rogue Squadron is only $10 on Steam; and Battle for Naboo seems to be abandonware, but it seems to be hosted on a lot of “better spread than dead” game sites.
They also usually use some weasel words like “up to.” That way, if it doesn’t last the full 72 hours (which it won’t), they can claim that they stated “72 hours MAXIMUM” rather than just “72 hours.” It’s basically shifts the statement from “lasts three days” to “definitely won’t last four days.”
