Looks like Torque has a good marketing team, the site makes the product appear very promising and professional. But refering to ratchet I'd talk to some users first. All the published games look like arcarde games (I see n oAAA title published with Torque) and each engine (IPad, XBox, Wii, PC, 2D, ...) costs money on its own.

I myself will wait for some reports on the engine in this forum and so far, I'll keep using 3dgs.
