He plays it all the time. My twitter feed's hooked to when he tweets and 60% of the time it's about BA. The other remaining 40% can be attributed to Gundam or gunpla (including 30 Minute Missions), his random thoughts, posts about the serialization, other games like Monster Hunter, and many more.I've always been curious why the author took such a drastic turn in genres for this manga. Seeing he plays BA explains everything lol.
