Well we all know how much you enjoy giving EA your money, but really the only worry to have with regards to a F2P game is whether or not it’s pay to win. Can you buy something ridiculously powerful with cash which non paying players cannot realistically ever attain? The moment a game allows that to happen it’s dead in the water, and PS2 is not like that at all.
Actually all the default weapons are amongst the best and most versatile options you can get, with anything purchased through XP or cash, simply representing sidegrades (with the odd exception – but these can be unlocked through play anyway). The only thing paying cash gains you is a quicker progression, and if you enjoy the game as much as I do, paying cash to unlock some guns is well worth the time saving, but by no means is it necessary. I’ve probably spent the same amount of money on PS2 as I did on BF3, and probably spent the same amount of time on both games as things stand just now….with much more PS2 to come in the future.
