I have just picked up Titanium and would like to start coding some games for the iPad.
I have, however, some concerns around the graphics capabilities, especially considering this post:
It would be nice to see some examples of how to best render 2D graphics as I would like to write a game similar to top-down games, such as Flight Control.
Titanium is awesome; it is truly an amazing time saver, and all but indistinguishable from natively written apps that use native UI controls. However, if you're looking for sprites, collision detection, game-like audio triggers, etc., I would highly recommend you look at a dedicated game engine (e.g., Unity 3D for, um, 3D, and perhaps Ansca Corona for 2D)
