This one's been poking around since last week, but we haven't touched on it yet here on TUAW: Kingdom Lores is what looks to be a fully 3D, fantasy adventure game for the iPhone, and it looks hot. The game is being developed by Marco Giorgini, and uses a custom OpenGL rendering engine to let players do all the normal dungeon crawler stuff: kill monsters, run around, collect the loots, and generally be the fantasy hero. The game is available for download right now, though you do have to jailbreak the iPhone/iPod touch, and right now you've got to manually install the thing.
If you're not courageous enough to try and install it yourself (raises hand), there are a few videos available to show off how it plays, and while it is very clearly an early alpha, it does look like fun. Unfortunately, the chances that we'll see it in the App Store are about nil -- Giorgini doesn't even have a Mac, and he's doing it all using the Win toolchain.
Surely someone can get this guy a MacBook and a developer kit, right? Or at least get a port rolling? A year from now, we'll probably all be playing iPhone Spore and laughing at how primitive this looks, but right now, when it comes to running 3D on the iPhone, this is a dungeon we'd love to crawl.
