As the name suggests, the multiplayer is clearly BF4 with different game modes vehicles and guns (subtly different, not hugely).
It's a bit early to judge on one map with 2 game modes, but the rounds seem very short to me.
I'm guessing the SP campaign is secondary to the multiplayer as is the norm with BF games.
At maybe £20 they could encourage a lot of players and a lot of players is what they will need to make the game a success, but At £60 for premium they need to do a lot more.
One of the problems EA is producing for itself at the moment is that in the space of a year, they will have produced 3 different multiplayer games which are broadly similar, and run the CTE program for BF4 alongside BF4. This leaves the community spread thin across a number of games instead of really focusing on one good game.
They just keep on grinding these games out hoping you'll accept that the issues in the current game you have paid far too much for will be fixed in the next game you pay too much for. BF4 final DLC isn't out yet but we've had Titanfall and now this since. Fix the issues in BF4 then maybe, I'll be gullible enough to buy this.
