So Xbox has got mods for FO4 that were previously only available to PC users. This has been done before I believe in UT but not to this degree. It's a pretty huge milestone in gaming that's up there with x-platform play on Rocket League. So far I haven't seen many complaints and I'm a pretty active lurker on the FO4 reddit and official forums. It's coming to PS4 sometime this month and it's pretty fucking cool because the amount of content and bug fixes that the community make swamps what Bethesda will make. It will be interesting to see how this pans out and if other devs follow suit.
