I would recommend GAE because its camera is even better. It can zoom in and out using the mouse wheel and has no limits. The only problem is the turning and slanting the camera is odd. Slanting forward/back is reversed (w slants it back), rotating with a or d occasionally gets stuck and will spin until you hit the opposing key.
Still, GAE beats Glest's camera.
(As for Glest, you really SHOULD download the new version. Forgive my rudeness, but it is very STUPID not to).
