In an interview with Edge, From Software creative director Hidetaka Miyazaki admitted there were numerous bugs in Dark Souls, and apologized to fans for this.
"Yes, there were technical difficulties," he said. "I don't believe that it's okay to have them, but realistically speaking, it was quite a large-scale game--even in terms of budget and expectations. So we're very sorry for the trouble we've caused by our processing errors and bugs from Japan."
When asked about the likelihood of From Software creating another game in the Dark Souls universe, Miyazaki said he's not sure it will happen, or if fans will forgive the studio for previous technical issues.
"We don't even know if we'll have another chance," he said. "We have the confidence that we can improve from our mistakes this time and create an even better Dark world, but we don't know if the users will forgive us for the mistakes, so I cannot give an exact answer."
Technical issues do not spell doom for all large-scale games. The Fallout series, a franchise notorious for its widespread and sometimes comical bugs, has spawned numerous sequels despite these issues.
