Todd has admitted multiple times that "the Creation Engine" is based entirely around the technology used in Gamebryo. So much so that a few months before Skyrims announcement, they stated that they were using a heavily modified version of Gamebryo for their next game. Then they changed their story to state that they modified the engine so much that they are considering it a new engine and gave it a new name. Seriously, just take a look at some Skyrim screens and tell me that the game doesn't have a very "familiar" look to it. I'm not saying that the game doesn't look great, but it is definitely built around the same tech they have been using, albeit heavily modified.
If you want proof, here is quote from Todd directly off the Skyrim website: So yes, the game is still based around the tech from Gamebryo, it has just been heavily modified.
"Rewriting" each of those game systems could be as simple as minor tweaks or it may have been rewritten from scratch. Logically, if they literally rewrote every system from scratch, it would have been much easier to just license a new engine or create an entirely new one. They obviously wanted to keep what was familiar and what worked, and tweak it to suit their preferences. I personally think it is more of a marketing tool to avoid the negative stigma of the Gamebryo engine, but that is just me. Truth is, whether you want to admit or not, the game is based on Gamebryo.........hurrr durrr.
Majorly taken out of context, and an incredibly arrogant scale.
"being based around the technology" can mean anything, assuming you even quoted him correctly. By that standard everything is based around everything since most game engines are created in very similar fashions. The problem with Bethesda gamebryo was that it has been in such constant use and under such constant modification that the code base itself became rather unoptimized and disorganized. Being based around "Gamebyro technology" likely means that the game engine has been made to function in a similar method, such as utilizing the same format types or having a similar editor tool. This does not mean for a second that the two engines are anything alike in practical performance.
You can't piece together code to create a game engine. It jsut woudln't work. In most circumstances it's actually more work to heavily modify an engine than it is just to write your own from scratch. It's likely that the engine has just been created to operate and handle in a similar fashion to Gamebryo, that does not mean it's based on the shoddy code of Bethesda's Gamebryo.
Obviously the developers are not going to create a game engine with an interface aspect that operates in an entirely different fashion if they just spent the last 10 years working in Gamebryo, they'll create a new engine that's just as easy to work with. It still does not mean the engine itself "based on gamebryo" it is based on Gamebryo on concept only, not in the damn codework.
I looked at a Creation Kit video and it looks kinda sweet. Don't remember if the dialogue system was in it though
I have not heard any word of this.
