Bioware is good, but Obsidian did well on their own. You have to figure, Obsidian is a subcompany of Bioware and helped them on many projects. It's like how Free Radical (comprised mostly of the Rare team who worked on Goldeneye but not on Perfect Dark) went off and made the Timesplitters series (of which the last one is IN-fekkin-CREDIBLE.) Same genre, different approach. I like all three, really.
