I think it’s safe to say that mostly everyone uses My3G or 3G Unrestrictor to bypass Apple’s silly 20MB App Store download limit over 3G. But you might just want to take Apple’s advice when it comes to Riven, the 90’s-era sequel to the popular PC game, Myst.

That’s because Riven maxes out at a whopping 1 gigabyte. That’s right, an App Store App 1 gigabyte in size. Some of you might be hesitant to download that over Wifi, let alone 3G…

Right out of the gate, before you can even read a description of the game, the developers have this to say:

PLEASE READ THE IMPORTANT NOTE BELOW REGARDING THE SIZE OF RIVEN!

And even if you do manage to download the game, you’ll have to wait an additional 15 minutes or so before it finishes installing.

The developers say that Riven is the biggest app that they know of, but right off the bat I can certainly think of a bigger app download — NAVIGON MobileNavigator Europe. You thought 1 gigabyte was big? Try 1.8 gigabyte on for size.

Regardless, it’s probably not a good idea to download either over 3G, especially if you’re not on an unlimited data plan. What do you think? Should there be a limit to App Store App size, or are you okay with whatever developers decide to do?

Riven can be downloaded from the App Store for $5.99.
