I have Fallout: New Vegas and Fallout 3 on steam and I want to try TTW mod (F3 into new vegas)
That mod is for Fallout: New Vegas and I would like to know if there is any way to start falloutnv.exe via falloutlauncher.exe (F3 launcher)

    What you're suggesting doesn't make sense. The TTW mod changes your Fallout: New Vegas install, it doesn't change Fallout 3. To play the TTW mod you need to start Fallout: New Vegas.

  • Theoretically, you can. Just move all gamefiles over and rename the .exe accordingly. But it is kind of futile. The mod is for FNV. So play FNV. I don't see the issue here.

    Technically it's possible but you'd break Fallout 3 in the process for literally no gain.

    @Robotnik The two comments at the top seem to be doing a pretty good job of explaining why the Unclear votes are happening.

As others have mentioned, the Tales of Two Wastelands (TTW) mod is a mod that brings the content of Fallout 3 into Fallout: New Vegas. You have to start Fallout: New Vegas in order to get it to work.

What is Tale of Two Wastelands (TTW)?

Tale of Two Wastelands (TTW) is a project that seeks to merge the content from the popular video game Fallout 3 into the more modern game engine of Fallout New Vegas so that both games can be played in the Fallout New Vegas engine.

If it was possible to use TTW mod and the Fallout 3 launcher, you would need to install the TTW mod into Fallout 3. Even if we ignore how much stuff would break when TTW loads up and starts looking for New Vegas items and objects, this would also just bring all the Fallout 3 content into... Fallout 3. No New Vegas stuff would carry over, it would be an exercise in futility.

  • I'm confused... doesn't New Vegas use the same engine as Fallout 3?

    @Powerlord - similar yes, however New Vegas is more polished and has less bugs. The whole point of the TTW mod is to bring Fallout 3 into NV so it can take advantage of the newer engine, therefore launching it with Fallout 3 makes no sense

The only reason I can conceive of doing this, is an attempt to preserve your F3 FOMM settings (or to use a mod that's not compatible with NV.esm, without which TTW won't work anyway). You have to import all that into NV's FOMM/GeMM list.

Here's the important part of my load order for NV, with TTW, using NVSE to launch it:
