No. New Vegas was alright because they received all the assets and engine of Failout 3 from Bethesda, so they could focus on their strengths rather than creating everything from scratch. If Obsidian had to make Skyrim from scratch, it would be completely doomed.
i agree, i actually meant that obsidian should be given the chance to make their version now that skyrim is released, ala New Vegas.
obsidian has, imo, been more successful at improving someone else's basic structure, than creating their own complete product from scratch.
