I left out the rest because Tomb Raider wasa just an example being brought up in the "quality control" debate. In other words, the point I made is that Sony does have some sort of quality control as proved by the above arguement.
To the arguement of it being devoted to bugs/playability only: well, the process does take about 4 weeks and after this time, Sony can either aprove the game or not. For example if the content is rather sick, Sony has every right to refuse aproval. Also in other words, if a developer claims certain things (for example in an exclusivity contract), Sony has every right to refuse aproval due to gameplay issues and other things.
Facts? Go look for a article regarding the game "Thrill Kill" which was denied aproval due to content. This already proves that Sony does care on what goes on sale and what not.
Another thing to think about regarding Tomb Raider being delayed. Do you honestly believe, if Sony denied the game because of gameplay, that Core/Eidos will openly say this to the public? Yeah, we\'re sorry for having Tomb Raider delayed, but Sony denied aproval because we failed to keep our promises.... As you see, Tomb Raider will remain speculation and sadly, we\'ll never know for sure why this game was delayed. Thrill Kill however should be indication enough that Sony doesn\'t aprove any games content - but it\'s no indication to how strict they are, what they tolerate and what not. As I also stated, no one ever said that Sony is as strict as Nintendo (once?) was, but simply that they do care enough to deny a game if its putting their name/image/position at stake or could bring them an advantage in those areas.
