The newly-revealed Gotham Knights certainly looks promising in terms of presentation and story, but some fans are rightfully a bit concerned about the game’s new RPG-like approach. Would the introduction of enemy levels limit your freedom, as has been the case in recent Assassin’s Creed games? Is developer WB Games Montreal planning to take a games-as-a-service approach with Gotham Knights?

Thankfully, Gotham Knights senior producer Fleur Marty and creative director Patrick Redding dispelled most of these concerns in a new IGN interview. According to Marty, Gotham Knights has specifically been designed to not be a GaaS-style experience.
