I read the initial quote but I gotta say,
If you rank Polyphony over Insomniac this generation it just seems very illogical. They've only released GT5:Prologue and that's it! Yeah they are working on GT5 which might be the best racer ever, but it is taking them like 6 years to make it. I bet if Insomniac put all that time into making resistance 1, it could have been a 100% rating. But it's nonsense, because if it takes you so long to make a game then you aren't really a high quality developer(on that system), because it takes you so long to get the job done.
Santa Monica has only made God of War 3 (and a nonessential port), which is a good game but how can a single game compete with several games that have been developed by Insomniac? It doesn't make any sense. You can make the quality of quantity point, but Insomniac games are quality! Maybe not 95% but still they aren't anything to laugh at at all.
Now Naughty Dog, I guess I can let that one slide. But still, we are aruing we knows the system more, it's not about who has made the single most high quality game.
