It is a great game based on exploration and creativity, though flawed, there's hardly anything quite like it in the market and if you're willing to put the time, you'll find yourself within one of the best open worlds we've seen so far. As I said, there are flaws for sure and they deserve some criticism, but that overall package is very solid and of high quality.
Nah, gameplay is superb, it's the reason I kept coming back to it for 10 full playthroughs. Seeing how much they're improving it in Part II makes me even more excited for it.
