You gotta appreciate the effort to make a decent police/firefighter/ambulance simulator for once, but man is this game uninspiring. Even considering that it's an early access game (so no, no complains here about bugs, aboout one and a half character and vehicle customization options, etc.), it's got next to nothing to offer you except for mediocre at best controls and basic satisfaction of "go there, arrestz em, grab em, put em in your car, drive em back to the station and turn em in". It sounds more or less like actual policeman's job, but after some 4-5 calls you get bored so much you just wanna run your face over the keyboard in desperate hope of diversifying your gameplay at least in some way.
The firefighter and ambulance gameplays are riddled with the same exact issues. You just end up wishing this game had at least something more to it when you play, more life, more diversity.
