they licenses the gamebryo engine they can do with it as they please. That said your gonna try and tell me wiki is a good source i could go change it to say Id tech 5 i bet alot of ppl would go OMG AWESOME if i did so
point is base code is still based on Oblivion / Net immerse. I dont really have any faith in bethesdas game engine abilities now again if it had been id tech messing with an engine id be alot more enthusiastic but this regular ol bethesda the same bethesda that is still using shadermodel 2.0 5 years after 3.0 was introduced.
there gonna take the cheapest easiest route they can to get from point a to b and get the game done. That means they took a prebuilt engine and customized it a bit but if they can do that well why not fix the inherent issues in all there games up to this point? dosent make sense dosent add up. Im sure the game will be decent enough but again the mod community is gonna have to fix 90% of the fuck ups like always.
Morrowind = Net Immerse - same base code as Gamebryo but original written at the time for DX 8.1 code was incorrporated into Gamebryo when Net Immerse was bought out.
Oblivion = Gamebryo
Fallout 3 = Gamebryo
New Vegas = Gamebryo
Skyrim = tweaked Gamebryo
another game that uses Gamebryo
Ego Draconis flames of vengence otherwise known as Divinity II looks awfully similar dosent it lol
I highly doubt Bethesdas skills in game engine development simply because the game below looks better then there previous titles and surprisingly runs better without the same issues. hmmmm interesting.
Besides id rather be a Pessimist at least if the game does suck i wont be broken up about it and if it kicks ass ill be even more thrilled so in that sense its a win win for me
