This really is comparing apples, oranges and pears.
* The PS1 was created pretty much entirely because Nintendo screwed Sony on developing a disc based gaming console - in this era, Sony were willing to take chances because they didn't really know the market well, so they had to spread their effort. Some great games, a lot of shit ones.
*PS2 was such a leap forward in gaming that it held crushing market dominance over the gamecube and latecomer xbox - they had a huge range because all the 3rd party devs coded for the playstation first and foremost. A lot of great games, a forgotten mountain of poor ones.
*PS3 was beaten to market by the 360, so it was playing catchup from day one. Games these days are MUCH more expensive to make, and the industry as a whole has become much less risk averse. Some truly great games, some crap ones, but less games overall due to price of production.
The comparison of these 3 systems seems to mirror the history of console gaming as a whole over the last 15 years, so why limit the discussion to how shit the PS3 is? This seems an awful lot like trollbait. You know that the xbox fanboys will come running, and then the PS fanboys will defend, and then it's THAT thread again..
TL;DR - no vs threads
