Care to elaborate?
Im tempted to pick both up, have read BF4 is pretty solid now and Hardline is pretty decent. That not the case?
If you played the older Battlefields games and are looking for Battlefield experience I would stick with Battlefield 4 and get the expansions instead of buying hardline, the BF4 issues that plagued it at launch have been fixed.
Hardline single player sucks the story is cliche and very repetitive, the AI teammates are completely useless they hardly shoot enemy & when they do, they take dark age to kill them BF4 story was not great either but this is much worse.
The multiplayer feels like dumbed down version or BF4 that has just been re skinned, the only reason to consider it if you enjoy the heist mode which is fun. VIP game mode is a joke u can run from point A to B and the game is over in seconds, hotwire another new game mode sucks you just drive around in circles around the map to win.
They may have fixed the above issues with VIP and hotwire but I have not played since launch, the multiplayer just felt dumbed down, lacking in content (hardly any weapons).
