Alexjh, while I would be inclined to agree with you, I have toured Obsidian's studio twice, and I've seen their mocap room I'm also friends with a few people there, just not anyone on the P.E. team. And I'm very aware of the dramatic flare added to movements, but I can tell you that by following the correct movements, it actually makes the combat look more interesting and flow together much better. There is a well written article in this issue of Game Developer magazine talking about it, with a compelling argument for why game developers should consider it. I wouldn't usually ask a developer to consider this, but I really like Obsidian, they've done a lot for me as a student, and I would like to give back while making a game better.
Then why are you posting on the forums and not contacting your "friends" at Obsidian about this? "If" being the operative term here. Considering the OP's claim to have "friends" at Obsidian, his choice to make this proposal on the forums makes that claim questionable at best. There was no apparent motion-captured animation in NV and they likely had a close to AAA budget for that. I find it highly unlikely that the OP has toured their offices, that Obsidian has their own motion capture studio, or that he is "friends" with multiple (or any,) Obsidian employees. If any of this were true he would have to be exceptionally mentally disabled to choose to post on the forums effectively anonymously rather than using direct lines of communication to his "friends."
Hahahahahahaha this is way too funny. Oh internets, how strange you are. As I believe I posted, I contacted my "friends" first, however they are working on other titles at Obsidian right now, and contrary to what you may believe, the entire studio doesn't sit around talking to each other every day, they're divided up into different areas. I was told that I should try the forum to get in touch with the guys working on P.E. Your naivete about Obsidian and the game development business as a whole did make for a good laugh though.
