This Reddit thread about the PC version of the beta is… not good. No ultra-wide monitor support is brutal. Voice chat not being push-to-talk is insane, and voice chat turning back on every time you load up is likely going to get fixed/changed, but if not, holy shit is that bad. And since its all online, you can’t mod the game to fix the usual issues Bethesda games have, especially at launch.
The above is reason enough for me to put off buying the game, especially since it won’t be on Steam so that’s yet another hurdle to jump over. Luckily I know I’ll be playing Battle Brothers with the new DLC around this time, so I won’t be dying for something to play. And with time, I’m hoping F76 gets fixed up enough to justify buying a non-Steam game, especially because I suspect the actual content/gameplay of F76 will be solid.

I look forward to hearing your thoughts on Fallout 76 once the BETA has crawled out of literally-minimum-viable-product status :D

they said there will be mods…

in online game … mods … surely nothing can go wrong…
Mods won’t come until private servers come, and that won’t be for a while. The big problem with no mods at launch is that A LOT of the usual Bethesda launch issues ARE fixed with mods on day one. Happened in Skyrim, happened in Fallout 4. In Fallout 76 players will have to wait for Bethesda themselves to fix the launch issues, and I suspect they won’t be nearly as fast or effective as modders.
I am still having fun making mods for Fallout 4. I don’t know about other Bethesda games but Fallout 4 has an Unofficial Fallout 4 Patch mod with hundreds of fixes in it. Some of them serious issues but Bethesda has never bothered to address the bugs in an official release even though bugs date back before the first DLC.
