I first saw Pocket Planes, Nimblebit's next freemium title, running at GDC earlier this year. Being a huge fan of both Pocket Frogs and Tiny Tower, I can't wait to see it in action on my iPhone and iPad. Unfortunately, the game's not out yet (it's still "coming soon"), but Nimblebit has released a trailer below, so you can at least see what the game is like and how it plays.
The game uses the same 8-bit aesthetic and characters as Tiny Tower, but instead of building floors in a building, you're growing an empire of airplanes, flying them around the world for fun and profit. You'll need to build up both planes and airports, and different types of planes fly at different speeds and have different fuel capacities, which can limit how far they can travel.
The game looks really fun. It's a little more complicated than Tiny Tower, but shouldn't be any less addictive. As soon as it's on the App Store, we'll let you know.
