Producer Daisuke Uchi said Japanese developer From Software was inexperienced in PC ports and didn't anticipate how difficult the process would become.
"In terms of technical difficulties obviously us being a Japanese publisher and a Japanese developer, the PC market in Japan is so small that we hadn't had very much experience," he told Digital Spy.
"So honestly speaking, we hadn't perceived how much trouble the PC version was going to be. We did have so many things we had to decide, so many things we had to talk about and discuss.
"It was a great experience but it was a rough ride to be honest in terms of being able to simply port the console version to the PC.
"But I believe that this experience and this occasion will be very helpful in anything else that we create on the PC."
Uchi added that while From Software has yet to consider future projects, it will now consider developing for PC alongside consoles.
"To be frank with you anything after that we haven't talked at all, and there hasn't been any talk on what is happening after this PC version.
"But at the same time, knowing that the PC market is important and with this experience, regardless of what kind of project we work with we probably will have a PC version in mind if we do decide to do it."
