Bethesda have gotten a lot of stick for the PS3 version of Skyrim, with its many bugs and sometimes unplayable frame rates and extortionate load times.
Bethesda, owned by ZeniMax,
ID, owned by ZeniMax...
ID is famous for creating amazing engines (ID Tech 5, ie RAGE) Which runs pretty well on all formats, why dont Zenimax use ID to create a company engine that all their dev teams can use. Why didn't Bethesda use ID Tech 5 (which I think was rumored at one point) for Skyrim? As ID has proven that they are not really up to scratch creating and open world game (RAGE was considered open world by the critics and fans but denied by ID). With ID's amazing ability to create working engines that runs almost perfectly (**cough**AMD DRIVER BUG**cough**) coupling this with Bethesda's ability to create amazing open world games this combination could create something truly amazing.
Instead ZeniMax have ID working on Doom 4, which I am excited for, but I would of much prefered Doom 4 instead of RAGE as I did like RAGE for what it was it just seemed to be a needless and pointless game to use the new engine on.
