This is a quick one (hey it is Sunday!). Thanks to Eric from porknbunny.com, I was made known about the "FREE for a while" thingy that is on at Unity3D.
Unity3D is an AWESOME tool for 3D games creation, with a model of the write-once-deploy-anywhere type. You can make superb 3D games with it, and make it into a stand alone Window's game, a web browser game, an iOS game, an Android game, and many other output options.
Unity3D has been free for a while now for small Indie developers, but the iOS and Android add-on would knock you back $400 EACH. For now though, the add-ons are FREE! An amazing saving of $800!
Well, I might be wrong, and I might have missed a T&C somewhere about the free, but what the heck. Go get it!
Please be warned that games made with Unity3D will require at least an ArmV7 processor to run. If you don't have such a device, I'd suggest you still go get the free version for now. Who knows when you'd upgrade eh?
