This game feels like the very early stages of something that could be pretty great.
It's trying to do a lot and the net result so far is that none of it is done amazingly well, but with some refinement and updating Enforcer could set a nice bar for police simming.
The cases, actions and procedures could do with some more fleshing out and there's not much by way of living world ambience. There are about 6 skins that all the citizens use and all anyone does is walk around with or without an umbrella as rain dictates. The world, while big, does start to feel very empty very quickly. Case in point; any house you have to go to; be it for a kidnapping call, possible burglary etc. is always empty of objects and any pertinent NPCs, crim or victim, is always standing in exactly the same position. Enforcer gets very 'paint by numbers' very quickly.
There are a few bugs, glitches and the car physics leaves a little to be desired but nothing here that kills the game. Sound is OK. Could definitely do with more 'ambient' noise. Street noise, cafe chatter around towns and just general 'life!'.
I've played a few hours and progressed up a few ranks (despite an increase in pay there's not really any difference in gameplay that I've noticed) ... i enjoy the missions and there is some variation among them but once you've done each one once, there's not a lot of pull to keep repeating them.
I guess in short, this game just needs an injection of 'life'.
