No offense intended dude, but you seem caught up in Obsidian and TSL. I think you should take Bioware and it's game a little more into consideration here. Bioware is known highly for great stories and gameplay. Just look at Jade Empire. That was a great game. Obsidian did do well on TSL as far as continuing the story, and improving the gameplay variety. But they lacked in a few areas like progression and endings. It's ending reminds me of The Sopranos! I'm just saying you should look at both angles very carefully before making a judgement. And that's why I say bring back Bioware.
Other than liking Obsidian's work, you took the words right out of my mouth. Bioware has an enormous amount of talent, experience, and storyline concepts to offer for any project that they work on.
