last interesting BF was BF2 - with coop-mode, bots, etc.
If you enjoy the graphics and lots of highly unrealistic modern pewpew on multiplayer: go get it.
Otherwise: save the money.
Single player is rather meh - stupid 'Murica propaganda movie turned into a game... fixed save points, no noteworthy decisions, replay-worth: zero.
Classic game to pirate: play once, marvel the funny details of the engine (frostbite 3 and the destruction mechanics - still quite something to look at), and uninstall...
