All the weapons are simplified, the maps are pretty much completely forgettable. 'Improvements' in graphics and visuals are actually drawbacks and inconveniences; too much visual clutter and pointless decor. Vehicles are terrible compared to BF2 and do not play anywhere near the same role. Movement and fundamental mechanics are far less responsive and are not as refined.
From a competitive POV BF3 is useless. BF2 was pretty damn good.
Yes this is what I meant... It is good when you first play it with the novelty factor but after maybe 100 hours you realise it is actually a very shallow game. Anyway no more BF3 talk because this is the CS:GO thread.
