please keep note that I rate this based on my taste, which are story-driven single-player games.
TLOU2 has amazing graphics, acting, and better fight scenes than TLOU (bc you now can approach a situation more creatively than before), but...
what's good about TLOU is the depth of each character they introduce. from tess, henry, sam, everyone that crossed Ellie and Joel's paths matters. in TLOU2, there were more characters, introduced too hastily, causing them to tell too many stories in a short amount of time. results are: nobody cared about the new characters. i can't even remember their names when they died. playing as/together with the new characters felt tedious and annoying, because you just don't care enough. emotional scenes don't work and feels like a drag, because you just don't care enough.
if you care less about the story but enjoy shooting zombies in a badass way, this game is for you.
