The argument can also be made that Beth and Zenimax pressured Obsidian to push the game out to early. That they were rushed in production and in testing to beat Fable 3 to the market. Assuming it's all Obsidian's fault is rather narrow minded, not to mention dead wrong.
An opinion is welcome, but kindly watch the inferred insult. I've been in media management for over 15 years, and in all forms of it, the responsibility of a project lies solely with the producer/developer. For good or for bad. "Pressure" is SOP, especially deadlines, and not an excuse for a product defects or poor quality. Despite the "pressures" that may have existed, which I am sure were many, if Obsidian failed to deliver under them, that is simply an indicator that they were unable to do so, or unwilling to do so. Either way, the onus lies with them and their inability to manage, scale and/or execute a strategy that would have brought this game to market in at least as stable a manner as Bethesda brought FO3 to market, despite the afforementioned deadline "push".
