For half off definitely give it a try. It's long been patched and when i played it early this year my only problems were two times the game randomly closed.

Gun play is extremely satisfying, sound design included.

Driving is... better than in watch_dogs, worse than in GTA. But traveling through the world is a bit disappointing. Rich map with little life.

Side missions are fun and fill up the time nicely. The missions are creative and not necessarily "go from point A to point B while killing waves of enemies", but those are there as well.
