I've played the first game and am halfway through the second. The games won all sorts of awards, largely because the storytelling is emphasized more than a typical game and it's pretty well written. From the trailers I've seen for the show, it appears to be really closely aligned to the game. Most games turned movies either don't perform well in terms of viewers, or they stray far from the source material in an effort to make a better movie. Many are calling this the best adaptation of a game into TV, ever. That's probably because the game was so story driven to begin with, making it an easier transition. I won't spoil anything, but there are many gritty moments in the games that I expect the HBO series will take full advantage of. But yes, the very beginning scenes of the game throw you right into a crazy world and have some wild scenes and plot points, so I can only assume the show is doing the same. I'll probably wait until the full season airs before buying HBO max so I can binge it quickly. I also saw they've already announced they'll do a second season, which I assume will be based on the second game, unless they've decided to stretch out the plot of the first game across 2 seasons.
