Fallout New Vegas

Yep, that's the one!

One caveat. When you use it to install a modlist, it offers to set up mo2 as a non-steam game for the modlist you downloaded. Which works great, and makes it easy to keep the lists separate.

But I found I prefer using this mo2 installer, which launches mo2 when you launch the game in steam, and then moving the mod list or changing my mo2's base directory path.

Both options work, so ignore that if you prefer the former or don't care. Just though I'd share.
