A portion of a Nintendo Life interview with Bandai Namco Producer Kensuke Tsukanaka ...
NL: Was it a notable logistical challenge to collaborate with both Capcom and SEGA in crossing over their respective IPs? And in terms of this sequel, has including Nintendo and developer Monolith Soft's characters added to the challenge when producing this game?
Kensuke Tsukanaka: We put as much care as possible into the IPs from Capcom and SEGA, and also had a lot of communication with them on how to handle their important characters and titles. Of course, Project X Zone 2 is a title which could not have been realized without their kind support. Moreover, characters from Nintendo titles join the rest in this game, which meant we had to be even more thoughtful - but including such great franchises from these three publishers gave us many possibilities and helped us realise this fantastic crossover in Project X Zone 2. We're really happy about this, and I believe this is one of the great cross-overs in recent years.
NL: Is this crossover franchise a series you hope to continue for years to come, or is there a finite plan for this run of games?
Kensuke Tsukanaka: I personally would like to continue such a cross-over series game even though this kind of game is not that easy to realize each time. Additionally, I would really just like all players to try the game and hopefully enjoy playing it – and as a result of Project X Zone 2, if players demand another crossover game, we're happy to start planning the next one!
