I know it is cliche to say but it took me the longest time to really knuckle down and play it, but boy once I did - I basically started up another playthrough right after to see what I missed and the shift in perspective when I played a different type of character was interesting to say the least.
So started as a skeptical intellectual who had to pull themselves from a sorry cop to a regular cop and approached things logically with a touch of eccentricity and pangs of regret and then compared to a wishy-washy communist with fascist leanings (which characters called the character out on) psychic superstar cop with an alias he truly believed was his name and I enjoyed and saw a completely different side of the game which was unexpected.
