Obviously not, but that's not what he meant. Beth makes open world, freeform, sandbox RPGs, and Obsidian makes more story driven games. There's nothing wrong with Obsidian's approach, of course, but some of us prefer Beth style freeform RPGs.
Obsidian is far less likely to depart from what Fallout was created to be in that department (a balance between story and non-linear gameplay) than Bethesda is; these are the guys who worked on the first two games after all. Personally I prefer that balance, if you focus too much on story than the game comes across as long winded and a boring experience (see post-Neverwinter Nights BioWare), but if you focus entirely on non-linear gameplay than it all comes down to grinding and LARPing neither of which appeal to most RPG gamers.
KOTOR 2 was the only game pushed out unfinished, thanks to LucasArts. NWN2 just wasn't great, especially the ending, but then again, FO3's original ending was pretty lame, too. Didn't stop the game from being successful, so I guess endings are overrated. Heh.
NWN 2 was a great game; it wasn't the greatest game ever but the campaign was definitely better than NWN 1's, and it was probably one of the better RPGs to come out around that time. Mask of the Betrayer was also a great title; it had a strong storyline, and very atmospheric environments. Storm of Zehir not so much, but I respect what Obsidian was trying to accomplish with SoZ (experimenting with new gameplay mechanics, and creating a more traditional hack and slash campaign). It's a matter of taste really, but NWN 2 definitely wasn't a bad game by any stretch of the word as Orc caves aside I personally thought it was a very enjoyable experience. Mask of the Betrayer showed that Obsidian still had it from a narrative perspective, and Storm of Zehir showed that Obsidian was willing to take risks which most modern developers are not (Bethesda included).
