This article does not cover that fact that globally game prices have increased.
For decades the average price of a AAA game tile has been around $60, going back to Atari and NES generations.
This was when a single person or small team could code a game in a few weeks or months.Now it take teams of people, Animators, programmers, writers, voice actors, even live action actors, play testers and a tonne more, all working for a couple of years to make a game that sells for the same price it did almost 30years ago.
Now you can see why company's are milking the DLC and subscription services and in-game purchases. I don't like it but I see why they do it.
So gaming in SA has gotten more expensive but so has every where else.
However online game services like Steam and Origin now charge in Rands and as such games are cheaper than before and if you patient and don't have to play a game as soon as it comes out then gaming is cheaper than ever.
Oh and keep and eye open,the Steam Summer/Winter sale should be hitting soon.
