I get hating Fallout 3. I hate how it (and every subsequent Bethesda Fallout game) has done irreparable damage to the Fallout lore. I think its main story is pretty shit and the only reason it's not a steaming pile of shit is because somehow Fallout 4 was able to surpass Fallout 3 in shittiness.

But you have to have your head pretty far up your ass if you think people wouldn't actually enjoy it. It's a good game (a bit dated by today's standards), it's just not a good Fallout game. And the people who love Fallout 3 don't care about the reasons that make it a bad Fallout game.
