I put 12 hours in the beta and about 6 since launch. It's nothing at all what I hoped it would be and it isn't remotely what I would expect from a full price game. The engine reworks didn't seem to fix anything at all and the stereotypical Bethesda bugs are present, which before wasn't an issue because it was single player but now that it's not, it's become a big issue with exploits, random glitches, quests and events not providing rewards, poor navmesh's and NPC AI, etc... Not to mention the half-baked features and ones that weren't/aren't there to begin with.
Above all, my absolute biggest issue, is the game looks no different from Fallout 4 as far as graphics quality/fidelity goes, yet somehow runs like complete and total horseshit. My rig has trouble keeping 60FPS at 1440p on the lowest possible settings. Not to mention I can't turn VSync off or the DOF effects or motion blur or any of that crap because Bethesda didn't pull that into the game menus from the .ini file (yet another issue generated by taking a franchise and engine and features that worked fine in singleplayer and porting it to multiplayer).
In short, I honestly want a refund but I won't ask for one in the hopes the game gets substantial patches and fixes down the road (plus I got the Power Armor edition and I like my collectibles at least (despite the helmet being cheap and the Duffle Kerfluffle©).
