Pokemon X and Y won't be given patches with balance updates, Game Freak has said.
Game director Junichi Masuda explained that although imbalances "could happen", as with previous entries in the series, he believes the team has "got it right" this time.
"We don't really plan to release any kind of updates to change the balance," he told Digital Spy.
"Of course, we think we have it perfect this time, but thought that before and depending on certain move combinations.
"For example, at points a lot of people used the Metal Grass Pokemon because they were so strong - and everyone is using that Pokemon.
"Something like that could happen, and we think we have it perfect, and we don't plan to release any kind of balance changes."
He added: "We spent a lot of time working on getting this balance right, but of course we're not going to be able to know everything's perfect until the games are in players' hands and they're coming up with new strategics and combo."
