For people complaining about USA vs UK pricing it's very simple.
Make a US account and buy all future games off that when you know you want all the DLC and expansions.
I paid $80 for Destiny Premium Digital Guardian edition or whatever it was @ launch which included all the DLC plus premium goodies such as the red ghost, etc.
I will now pay $40 for the expansion.
Convert those prices into pounds and I am effectively getting this expansion for free compared to those that bought the same edition I did on the UK store.
It's always been this way. Pair of Timberland boots in UK is £180 in America $180. Headphones which cost £400 here are $400 in America. This shouldn't be a surprise to anybody. One of the reasons is taxation, we have higher tax here than in America. People will then say VAT is only 20% it's higher tax on everything though not just VAT. Higher wages for those truck drivers that transport them across the UK. Higher tax/duty on the fuel which goes into those lorries that transport them across the UK. Higher wages on the staff that pack orders, stack shelves, etc, etc. Basically everything is more expensive in the UK because everything costs more here. Staff cost more, fuel costs more, tax is more, duty is more, etc. It's a combination of all those things which makes prices higher. The end result is we have a stronger currency and economy compared to the US. Yes there economy is bigger but it's also weaker. They don't get free health care, prescriptions, university fees (Scotland), etc, etc. We pay more and we get more benefits in the long run.
On another note I think about how this one game has stopped me buying others (I have bought others but never played them because of Destiny and because of that it's stopped me from buying more).
I don't play as much as I used to but I still play regularly enough to justify spending £25 on the next expansion.
I will easily bow £100-£200 on a night out. Which is what 4-8 hours of fun. £25 for another 50+ hours of fun seems like a no brainer to me.
