actually its the other way around, now more than ever since Bioware was bought by EA
Umm........ok.
Today Obsidian has more in common with Black ISle than Bioware, while Bioware managed to get a better profile on their new name, Obsidian is better in a lot of things by now, however this will only manifest in the minds of the people in the coming 5 years
let me rephrase myself: "The isle was made of black obsidian"
OK, but right now Bioware is a giant and Obsidian are yet to really make their mark, and by that I mean having a really big hit.
