OG is good shit man
It's WAY more challenging to get to spots and what not but the city was worth it.
I like the first city the most so it's funny that you like the third one but I guess you started later than we did with it.
It was all we knew at first but the flick it controls were so dope it didn't matter.
You would probably be in the same boat had you been here at launch.
Don't let the lack of mobility discourage you man, OG is too much fun.
