EA Sports has responded to Konami’s assertions that FIFA stole wholesale from the PES series.

Last month, Konami's Jon Murphy accused the FIFA team of ripping off many features from PES, and claimed that EA's dominance was only due to exclusive licences and a larger budget.

“They have a long history of copying PES to get to where they want to be. People shouldn't forget that's how they got where they are,” said Murphy.

EA Sports’ general manager and vice president of football Matt Bilbey said he "didn't think that much" about the accusations, but that the rivalry between the franchises had benefitted EA hugely.

"We were fortunate to have Konami as a competitor, because it motivates you - you can't win unless there's someone to beat," he said.

"I hope the [Konami] management team in Japan appreciate what [Jon Murphy has] been giving to that franchise for a long, long time. He's very, very committed and a great spokesman for the game.

"I feel for him sometimes, because I've worked with developers that it's challenging to listen to, or they don't necessarily listen to you."

Bilbey also mentioned that some within EA felt that the time it took to develop and implement features sank any claims of plagiarism.

Others in EA had only praise for their competitor.

“We're very respectful of PES and we understand we have a very strong competitor. We know they want to make a better game every year and ultimately that drives us forward,” said FIFA 13 producer Nick Channon.

EA Sports boss Andrew Wilson agreed.

"I had the great fortune of leading the [FIFA] team as we went head-to-head with Konami. I had the greatest amount of respect for them then; I thought they built a tremendous game. I continue to have the greatest amount of respect for them today."

This week EA settled a class action anti-trust lawsuit regarding exclusive licences, the terms of which stipulate that it must pay customers US$27 million (NZ$34 million) and not sign any exclusive licences for five years.
