While at first, I didn't really like Fallout4, 22 hours in, it's growing on me. It's super not linear. And you can choose your path, pretty much. While many things bothered me initially, getting a big picture overall really changes my perspective.
Yeah, the game has tons of bugs. People don't like the graphics, but it's a HUGE step up. The way feral ghouls run after you is incredible.
Lastly, I'm playing this on a radeon hd 6850, everything at low. And it works. Sometimes I get stutters, and very low frame rates, but usually it's fine. So don't take that minimum requirement of 7970 as absolute. It takes about 3 GB ram on average, but I have 32 so no big deal. I know I should get another graphic card, but I'm waiting for hbm2.
