Interestingly, I only used "accuse" like 5 times the entire game. Different strokes for different folks, I guess.
I guess it's sort of like GTA in that it's an big world with cops and bad guys, but GTA is a sandbox game while LA Noire is way more plot-driven and story-based, so of course you couldn't punch hookers because Cole Phelps would never hit a woman. I got pretty immersed in it and I liked it although there were times it felt like a chore to play. So I'd give it like a 8.3/10.
