Sales of 'Grand Theft Auto 5' will not be affected by 'Red Dead Redemption 2', according to developer Rockstar.

There are concerns that the two titles could eat into their share of the market when 'Red Dead Redemption 2' is released in 2018 - but CEO Strauss Zelnick is confident that won't be the case.

He said: "When there's more than one title in the marketplace that compels people, the market also expands to take advantage of it.

"The marketplace can be competitive, but it's rarely directly competitive title-to-title, whether that's a title that comes out under the Take-Two umbrella or any of our competitors or anything else for that matter."

Strauss insisted the firm is looking forward to the launch of the game - and is confident there won't be any major issues with it.

Speaking during an earnings call, Strauss shared: "We're really looking forward to the release of 'Red Dead Redemption 2'; we're really excited and enthusiastic, of course.

"We don't think that has anything to do at all with how 'Grand Theft Auto V' and 'Grand Theft Auto Online' will perform."

Strauss said something similar earlier this year, too.

He explained at the time: "All entertainment titles compete against every other possible use of your time and they don't compete specifically against our games or anyone else's games.

"They compete against everything, against text messaging, going to movies, reading a book, doing your work. Entertainment is a 'nice to have,' not a 'must have.'"
