There was a brief period about 18 months back when the rand collapsed and games were around R800. It lasted about a month, though, then games went back to R600 or so.
Generally speaking, however, EA games are a bit cheaper than other publishers'. Take2 and Kalahari sell them at R530, which is a great price.
Also, console gamers have the option of trading in and/or buying secondhand, which is also a nice way to save some cash. And as you've pointed out, there's no DRM to fuss with. That's worth quite a bit.
Jeez, where do you live? A ticket at most cinemas in Cape Town will cost you R40-50 or so. Add on petrol expenses the extortionate parking costs of any local shopping centre, and you're out about R70. And that's excluding popcorn. ;P
