For the most part. I'm more in it for the disagreements, which is as we all know the better part of discourse.
I prefer to believe that disagreement is the core of all discourse. It is kind of pointless to discuss something when you all have the exact same view point. I'm here to partake of the view points that others formulate on issues like this.
The benefits of Obsidian over Bethesda. Obsidian has some of the original writers and creators of Fallout and a lot of people feel that brings it closer to the roots and heritage of the original games. I don't see this as being particularly relevant. Fallout was an incredible game but it is being developed by Obsidian and not Interplay. The company has changed and isn't the entity it once was. Treat them as the company they are instead of what they partially grew from. After all, people change doc.
Beyond that, both companies have great reputations and lists of great games that have been produced. Morrowind is still a god among games in my mind and I'll always love Bethesda even if they start producing generic copies of the same game over and over again and again for the next 10 years (kind of like what Capcom has been doing with Street Fighter for years... Honestly Street Fighter 4 is less fun than Street Fighter 2 and they are just about the same game. Only with uglier characters, slower gameplay, only famous characters and characters that make no sense, aaaarrrrrgggggggg). ... but that is Capcom XD lol. Obsidian's game list is nothing but games I have fell in love with. Almost took KOTOR 2 into my bed once. My girlfriend made me put it back on the shelf v_v. I look forward to anything Obsidian produces like a love sick puppy (have been waiting patiently for Alpha Protocol since I pre-ordered in August of last year. Almost cried when it was delayed)
Bethesda's greatest attribute is in the creation of game engines that allow for the quick creation of these great worlds for the player to move through. Morrowind was the best example of this (I really felt like I could go anywhere and do anything). Obsidian's greatest attribute is within story and just awesome idea's. I believe that the mixture of Bethesda's engine with Obsidian's ideas should produce something incredible. Of course, you would think that since ice cream tastes great and steak tastes great then putting steak through the process of making ice cream would make something incredible right? ... I do wonder XD
