Had more time to play it, and I'm really enjoying it. Campaign is on rails, but still enjoyable, which is a rarity for me. I hardly ever play SP. SP graphics are gorgeous, btw.
Heist mode is a blast, but also total anarchy without team work. Players with ADD can't decide if they want to loot the central stash, raid the enemy stash, or protect their own stash. Still, it's fun.
Conquest modes are as good as ever. Conquest Large isn't as large as BF4, but in the absence of jets, it doesn't need to be. All that space in previous BF's were essentially for them. I actually prefer the new large: enough space between points, but not so much that huffing it between them is a chore.
Also enjoying the new unlock system, even though it's borrowed from Black Ops. If it works, it works.
Game is MUCH more stable than BF4 was at release. Haven't had a single stability issue, crash, etc.
