The simple answer is that a crash like '83 can't possibly happen again, the market is simply too diverse now. If a tipping point was reached because of micro transactions, bad will, what have you then those companies responsible would die. However, indie and proven A-AAA devs would fill the void. Even if consoles bit the dirt then the market would live on in PC until a PC dev became ambitious enough to inevitably start trying to make consoles again.
