Advance Wars is the best modern example http://i.testfreaks.com/images/products ... 484160.jpg
Notice the stylish but simple 2D art that's very effective. The reuse of terrain tiles and reuse of slightly isometric view 2D artwork. (with a tiny bit of animaton) Also the game is a tactical turn based strategy game with RPG elements, and a pretty good one. So although Wasteland 2's technical design will look like this, there would need to a much stronger emphasis on the RPG technical elements. For combat and exploration purposes though, advance wars visual setup works fine and looks good.
Clearly we are going top down and that it is likely to be isometric in nature. Some game engines have you bake the assets first which can give a better look while others have you render on the fly and give more latitude with camera work, and we are looking at several options here. I would imagine we will offer some different perspectives when it comes to dialogue.
To me he seems to be talking about what Advance wars does when it comes to dialogue, when two characters are talking to each other, and it does it very efficiently from a 'time to implement' view of things.
