You don't really know how game development works, do you? Are you sure you're not looking for something like GameGuru or Axis Game Factory? Seems to be more well suited for your expectations and skill set. T3D is not a nightmare, by a longshot. It was, however, completely abandoned for a long time. With the source release, it's slowly getting traction and being improved by the community. If you want to make a game with a few clicks, this is not the place. Never was, not even when it was a product.
