Police Force 2 is a vast improvement over some of its ilk, and has a fair few things to enjoy, but like so many of its kind - Utility Vehicle Simulator, for instance - it suffers from a number of flaws that make it a bit of a chore to play.
The most noticeable flaw is the graphics. PF2 is several generations behind the curve - it compares poorly with GTA San Andreas, a game almost a decade old. Configuration is minimal, and engine optimisation is very poor; a game this simple has no right to be this sluggish on a modern system.
Gameplay also has its flaws. Movement feels cumbersome, with both vehicle and pedestrian movement feeling like the roads are made of treacle, and map design is clunky. The mission structure is simplistic, minimap guidance is confusing at best, and there is little to draw one in.
That said, however, there is a fair amount of fun to be had. It's not huge fun, but dipping in for half an hour can be surprisingly enjoyable - I've come to think of it as Minesweeper with blues and twos. This is never going to be a great game, or even good; even eight or ten years ago it would have been described as competent, nothing more. But going in with the right expectations, and it can be good enough.
