(Please keep in mind, the tutorials teach you how to use the functions of the TE, and not how to make, "politically correct" terrains.)
That must be code for a working terrain with high frame rates + good game play + working strat + no mountains of water + randomized terrain tiles +...
There has never been such a thing as a "politically correct" terrain as far as I know, although I can imagine a few trivial instances that would violate the htc TOS rules. As with all things in AH, there are requirements to be met that are not achieved without effort.
The requirements in their order of importance, IMO are as follows:
1 Good game play design ie frame rates, distances between bases and objects etc.
2 Knowing the special requirements, if any, for the target arena.
3 Understanding of the interaction between the game components, ie truck convoys, ack etc.
4 Familiarity with the Terrain Editor (about to be updated).
Meeting those 4 requirements alone, you can produce welcome terrains for any arena including the AvA. The next two are of benefit to the AvA, but are not required.
5 Familiarity with the Object Editor (optional, and about to be updated)
6 Familiarity with ac3d (optional)
While Pearl Harbor is a worthy project, it's one that shouldn't be attempted as a first project. It's more fitting for a builders' 3rd or 4th project because of the additional components requiring the Object Editor and ac3d. I suggest something like the Poe Valley as a more fitting first time terrain building effort.
