Oh yes, definitely RAM heavy. I tried a few things with my tablet that caps at less than 1.5GB RAM, and after doing a few system tricks to lower the system usage to at least 800+MB, I could run the game fine, but it crashes every time it tries to return to the world map (which is set to the fast graphics setting). I am glad that crashes do not happen during events, but after they are done, which lets the autosave feature trigger on time for the crash. The game really needs more memory optimization, frankly speaking.
