Getting back on topic, I too feel that the planet sizes were much to small. There was really no exploring to be done. (Walk forward, turn left...ahh, star map).
I would hope that all the planets were at least equivalent to the size of Taris.
Please Obsidian, make the levels a more realistic size. I wouldn't mind if doing that would delay the release date for a bit. Afterall, the original KOTOR was delayed over 6 months. As long as the delay implies a better game, then go for it.
