Absolute poverty used to be defined as living on less than $1 per day (this has gone up to between $1.25 and $2.50), and over 3 billion people live on less than $2.50 a day. The US poverty line is around $10 per day. On the other side of the scale there are over 5 million households in the US that are millionaires. Now take any number you like for the cost of a game, be it a $60 console game, a $15 monthly subscription, or a $25 sparkle pony. The conclusion will always be the same: Games are too expensive for somebody who lives on $10 per day, but extremely cheap for a millionaire.
I do not think that anybody can really have a neutral perspective on that, because we all have varying incomes and savings (or debts) and thus all value money in different ways. Most of us are somewhere in the middle between the poverty line and the millionaires. But I must personally admit of considering the idea to buy a new iPad Air for $1,000, just to replace a slightly slower and slightly heavier iPad 3. So buying something in an item shop for $10 is not much of a hurdle for me, because that isn't "rent money" or "food money" I'm spending.
I consider the value of money to be relative. It depends on where you are in Maslow's hierarchy of needs. If you are high enough up, you'd consider statements like "Can't buy me love" to be truths. If the price of a game doesn't add or subtract from your ability to fulfill your needs, and that game fulfills a need of yours, the game is well worth it. If the price of a game means not being able to afford a more basic need in the hierarchy, then the game is too expensive.
