I remember buying Comanche again years after it was released. But it was unplayable. The fuel depletion rate was somehow proportional to CPU speed, so on my (relatively) faster computer, the helicopter would run out of gas just a couple minutes into the level.

This is true of a lot of DOS simulator style games from this era, where they often let the game systems run at uncapped rates. They were typically just targeting a specific 386 or 486 CPU etc, so performance was pretty predictable on the customer's end hardware at the time. Wing Commander 3 is another example that is famously bad for this. When faster CPUs inevitably came along, these games basically broke or played differently due to the speed change. Back in early 90s many 486 systems had a button on the case marked "turbo" so you could slow down your 486 to play games optimized for earlier chips at the correct speed.

Dosbox offers ability to adjust CPU "speed" to help with this today, but it's often hard to get emulation speed right on early DOS games that ran uncapped.
