I couldn't get into the Fallout series, in general, but I have also heard negative things about this one in particular.
I know several diehard Fallout fanatics who have tried it now.
Every single one has given up on it in disgust, for things ranging from ridiculous bugs that should NEVER be in a release (HOW DO YOU LEAVE THE SKYRIM OPENING IN THE GAME?!?) to the feel of being literally the only human alive to massive abuse of PvP mechanics for the sole purpose of griefing non-PvP players to absolutely zero-support of add-ins along the WoW style.
I've been a huge fan of the Fallout series ever since I first played the original, and while this is the first PC release I've ever missed, I'm glad I didn't waste my money on it.
