Great list plus one for you Serapth, but... Torque 3D no longer costs 179$, it now cost zero $ and is free under the MIT license. Regarding books, then two new useful books have seen the daylight:
- 3D game programming all in one third edition, Kenneth C. Finney
- Torque 3D game development cookbook, David Wyard
I sure hope the other information about other game engines are more up to date....
