It's a free mod for a fairly old game. They say it's a DLC sized mod but it actually feels like a brand new fallout entry. A lot of reviews are complaining and expecting them to "fix" the CTD issues.. What people don't seem to understand is all of those issues are already fixed. You just have to know how to mod fallout properly and install the apropriate fixes such as buffout. The fact some goobers are genuinely waiting for a "fix" is laughable at best. There are genuine issues with the mod but compared to other large scale fallout mods they're so minor that they can be completely over looked.
