While WA4 is clearly an unfinished game, in terms of the actual experience of playing it it's a huge step up from any of the previous ones. The combat and dungeons are actually fun and so are the character interactions. If you can accept the fact that it's only about half of the planned content and the plot ends up feeling pretty haphazard as a result, I think it's actually way better than people give it credit for and even manages to feel surprisingly modern.
