The developers at Shin’en truly know how to optimize their games. Despite being a visually intense game that has a lot of content, the game is only 900 MB on the system. This is something other developers can learn from, since optimizing your game well will lead to taking up less data, not inconveniencing players and thus getting more sales.
#FastRmx filesize is only around 900Megabyte.
So everyone can install it right away on Nintendo #Switch system memory without trouble! pic.twitter.com/yvc3IdVUgZ
