It's not like you can ask a level designer to start programming, or a programmer to write stories or design the game.
Those are all entirely different jobs.
I'm even pretty sure that the programming department has separate teams of experts working on various aspects (engine, effects, AI) of the game.
Game developers used to have small teams of multi talented people 20 years ago, but that's not how it works these days.
I think it's admirable for a game studio to develop a new engine from scratch.
A game has a lot more potential this way and I don't think it's fair to start criticizing that decision without even having seen one screenshot.
it was also admirable for the last clan of samurai to launch that final attack against the imperial Japanese army in The Last Samurai, but ultimately they were blown to pieces.
and its not like the employees would be doing a totally different job, more like adding and customising an already existing work.
There are far more things to a game engine than just graphics. But it must obviously be able to support huge open game worlds that aren't separated by levels and loading screens like Crysis.
But there's the AI (Oblivion keep track of it's ~3000 NPCs at all times), quest system, dialogue system, streaming capabilities, game building capabilities, debug features and so on. I'm not sure if many here can tell if whatever engine are well suited for large RPGs from that point of view, I sure don't. Instead the whole discussion here seem to be about making Skyrim pretty. But you can't base how well suited a game engine is for a certain game on graphics alone, which largely depends on the game artists anyway.
But if Bethesda used CryEngine, Unreal 3 Engine, Source or any popular engine, and built the game using the default tools that are supplied, the game world would be massive and would need several DVDs to be stored. In the past games Bethesda built their games with a plug-in system that proven to be very efficient when it comes to storage costs. What takes space in Oblivion are the voices and the textures, not the game world data (FalloutNV.esm is only 240MB). So they would have to rework several systems regardless.
yes, but all the npcs did was walk in a repeating circut.
and its not only making skyrim pretty, because they are probably already doing that. it is about choosing somthing that will make it pretty with a minimal amount of effort on their part so they can focus on other aspects, thus making the intended topic here to be how can bethesda maximise the content of the game while minimising time spent making that content prettier,
