Battlefield Bad Company 2 was well received and has sold millions of copies, but DICE executive producer Patrick Bach says he only sees faults with the game.
"I don't know why, but I always feel ashamed about the games I'm involved in making," he told the Wall Street Journal.
"I can't even bring myself to start up Battlefield Bad Company 2, our last game, because I feel so ashamed. I know it is a great product but still I only see the things we could have done better."
Bach also said the studio's in overdrive trying to perfect Battlefield 3 ahead of its release at the end of October.
"We are focusing on cutting the bad stuff rather than adding and changing things. Instead of adding ideas, we are removing problems, and that is what our testers are helping us with.
"We have deleted portions of maps, we have skipped passages in the single player campaign. Everything that doesn't meet our standards we chop out. A lot of games fail at that, they seem to think more is better and often, that isn't the case.
"Everyone in the team has been sucked into the idea that this will be the ultimate game. And when you feel that you have to ship a tiny detail which isn't perfect you feel extremely disappointed. But to be honest, when you look at the game it is pretty cool. You just have to step away from it."
You can get a taste of Battlefield 3's multiplayer component right now by downloading the beta, which opened up to the public earlier this week.
