Something is going to change within the next generation, like j-e-f-f-e-r-s said, triple-A gaming is just not sustainable.
Some people argue the pressures that caused the crash of 1983 no longer exist, but I'd say they still do and we are seeing a situation similar to that now.
Take Pac-man for the Atari 2600, it was rushed out and nowhere near as good as the arcade version. Atari estimated a huge number of sales but the quality of the rushed game drove away customers and they ended up selling half of their sales expectation. Doesn't this sound oddly familiar?
The main reason for the 1983 crash was the loss of customer confidence because of an explosion and saturation of new independent console manufacturers mixed with a drop in game quality from the best known producers of video games.
In essence Pac-Man for the Atari 2600 crashed gaming, nobody knew what was worth buying after that, if even Pac-Man is bad what could be good?
I really wonder if Simcity is EAs last fuck up before they truly decline in the same way, I mean really what haven't they fucked up as of late and what can we trust them not to fuck up within the next few years?
All we need is a few more consoles to enter the market at the same time as Sony and Microsoft(like the Piston and Ouya) for their projected sales to fall short and few rushed games on the magnitude of Simcity and we might very well be in a situation close to the 1983 crash.
I don't think we'll see that kind of a crash though, it all depends on how the industry reacts to the problem of rising costs and no security in sales numbers.
