BFH is a new game, but more like COD i guess, small maps & NO tank, jet, attack heli warfare. Its civilian vehicles vs civilian vehicles, no military stuff.
Since there's no big Pre-Order bonus stuffs, better wait for days for proper user reviews.
BFH is like BF4 v1.5 with small maps & Bf4 itself is like BF3 v.2
BFH seems like an extension of a "Close Quarters" DLC from BF3. & EA decided to make a game out of a DLC.
The games are too expensive for what they are worth, thats why i still feel BF3 was best bang for buck (Rs.999 at launch with free DLC). BF4 @ 3.5k is not worth it. I'm skipping BFH, and like rcuber said, many of our BF4 friends are skipping it too.
reg. bf4 on 7730m, my GT540m & i5 2340 still handles BF4 easily but at med settings.
