Like it or not, phone games are a thing. They're here, they're a part of the gaming ecosystem, and though they have not (and will not) kill off handhelds or consoles, they're going to continue to do their own little thing.
There's so many phones out there, spanning pretty much everything possible- from low budget microtransaction laden F2P 'games' to full fledged original AAA experiences developed exclusively for phones, and everything in between, including ports and companion games of major titles.
But which is the best phone game you have ever played? And why?
Oh, and bonus points if you name a title that was natively made for phones, as opposed to a game that is a port of an existing PC/console/handheld game (so try not to name stuff like GTA, The World Ends With You, and so on).
Anyway, my favorite phone game is Game Dev Story. I don't know how many of you have actually played or heard of the game, but it's pretty incredible, and addictive as crack- you take charge of a startup game company, you make games for various platforms, you see your corporation grow, until by the end, you are an industry behemoth, with your own hardware and a stable of AAA franchises. When I first started playing Game Dev Story, I got so hooked that I honestly think it's the reason my iPod Touch's battery died off as soon as it did.
