Epic's Unreal Engine 3 Ported to iPod Touch and iPhone 3GS - Mac Rumors Why are developers even bothering with Quake I, II etc. Clearly the Droid can handle unreal tournament 3 engine if the iphone can. I don't have much knowledge about porting but is it "easier" technically speaking to port older engines than newer ones(assuming that both are capable of being run on the target devices)? If it is, why is that? Is it because the older engine can be less polished and efficient due the the device's ability to compensate with its "overkill" hardware?
