Considering how things have worked out in the long-term for Bioware, they are probably not a good example to follow though.
What are you even talking about.
Bioware was a huge success througout ?
Commercially, yes. They did so by increasingly abandoning anything Baldur's Gate. Which lead to Dragon Age Origins initially being pitched as a "back to the roots" project, despite its measly 3 character classes to chose from, and several more cases of "streamlining". However, that remained that, one project. And contributed to veterans quitting as far as back then already. http://blog.brentknowles.com/2010/08/15/bioware-brent-year-10-fall-2008-summer-2009/
