Their engine and tool-set evolve with the game. They seem to be severely understaffed for their ambition. It was nice to hear that they are hiring some folks, even if that number is low - despite my knee jerk reaction around release predicting otherwise. I do believe Sony needs a studio like them to fill the gaps left-over by GT. They are very capable also - it's not like they're some left-over. Quality is showing, slowly but surely. Evo did learn an important lesson, whether that be the producers, directors and everyone in management involved: don't release a piece-meal game, you'll get hammered. Obviously the realities in the business make deadlines and delays extremely paramount to survival but so is avoiding fuck ups.
Will pick the game when everything is packaged into a definitive edition. Evo is setting the bar in the genre without anyone (majority) noticing it...truly a shame.
