I don't know about this but I htink it would be better if some achievements are kind of "broken down". What I mean is that there are certain achievement like doing 50 petties in every city where you do not know what cities you managed to reach 50 petties and those that you didn't. If you know which cities you should petty, it would be easier to gain an achievement.

This would help me a lot but I don't know about others.

I agree as I've never bothered to keep records of the events in such detail.

It becomes more frustrating with each higher level for a particular achievement as the amount of time required to do crimes in order to gain the 1% increase (minimum detectable level) can become quite large and therefore a lot of time uneccesarily spent doing so.

It's something i feel is unlikely to happen sadly, but you have my support all the same.

i think this would be a good addition to the game and i was gonna suggest it myself.

It would be easier, agreed, but that would take out the fun of it. Just figure out how many times you have to do it to get a 1% increase and then go to every city and test to see if that was the city needed. You'll get the points from the activity itself even if you don't get the achievement right away.
