Sucker Punch – ‘We Made Dumb Decisions’ with inFamous
Speaking exclusively to Play at its Seattle studio base, Sucker Punch has admitted that it made mistakes in how it made inFamous, but has learnt from them and made significant improvements for inFamous 2. Development director Chris Zimmerman revealed that the studio is now very familiar with the PS3 hardware and is fully prepared to exploit it to make inFamous 2 look the best it can.
“We made some really dumb decisions in the last game, but we’ve managed to fix them,” he told us. “It was pretty early on that we knew what we weren’t doing in inFamous that we needed to do in inFamous 2, but we had to tear a whole bunch of stuff up and put it back together. In technical terms the biggest thing that we’ve done is migrate a much larger part of our code to run on the SPUs. The PS3 has this elaborate architecture where there’s a whole bunch of different places you can have your code run and we had it all running in the slow part.”
By sussing out the hardware Sucker Punch believes it has a game that could never be achieved on another console. “If you look at games like Uncharted 2 that’s a game that you actually can’t do on Xbox no matter how clever you are, there’s just more processing power on the PS3,” Zimmerman explained. “inFamous 2 is going to be the same way. You’ll look at it and see that there’s no way we could have done this game on 360.”
I don't have any intention to post this because of only on PS3 thing but It will be posted here anyways so might as well post this right now.
