So i am an avid Fallout new vegas player and i recently wanted to buy the PC version only for the geck but then it turns out mine is to old and cant get a new one so i was thinking as a DLC Bethesda could add either a home builder us console people could share between us or just a general geck because i really like the look of the enclave commander mod

The GECK is not some novelty level-building program. It is the actual tool they used to make the game. It requires a bona-fide computer to use to any effect, from the mouse-keyboard input interface to the fact that SDKs always need more hardware power than the game itself.

So no.

What are your specs? You might get to run it on lowest settings.

And the GECK is an actual tool as stated. It would be much too complex for it to be ported.

A construction set for consoles won't happen, for a lot of reasons.

I'll leave this open, in case someone can help with suggestions for your pc.
